### Mathematical Practices:

The CCSS says this about Model with Mathematics, “In middle grades, a student might apply proportional reasoning to plan a school event or analyze a problem in the community.”
With the holidays, could you ask the students to Model with Math by asking  questions about how much food your household needs to buy to host a holiday party?
How do students demonstrate their conceptual understanding of mathematics in your classroom? What performance tasks do you have students work on?

How do we move up Bloom’s Taxonomy and go deeper with Depth of Knowledge (DOK)? What beginning PBL is available to help with DOK and Bloom’s?

#### Description

The Parchitecture Project

Using Google Sketch Up, students design a student play-area for the new High Tech High K-8 school in Chula Vista. Students create design firms, conduct student surveys for input on their design, determine budget costs, and propose their ideas to a panel of adults and peers. Students have complete control of the design of the space with the stipulation that it must be safe and accessible to all students.

A local charity needs your help!  You have been asked to plan a Family Fun Night in order to raise money for the charity.  You will develop games and find theoretical and experimental probability of each game.   You will plan a concession stand menu with combo choices, shop for game prizes and concession needs, and propose a layout for the event.  In the end, you will present a proposal to a panel of charity officials that includes the projected cost and profit for the event.
Let’s Party!

As caterers, students are bidding on a job to plan a birthday party for a 13-year old.  Given a budget of \$250, they will submit a party proposal for 30 guests that includes a budget spreadsheet, written description of party and events, menu, map of room, and an oral presentation.

### Mathematical Practices: Make sense of problems and persevere in solving them.

This tip comes from the ADE:

In grade 6, students solve problems involving ratios and rates and discuss how they solved them. Students solve real world problems through the application of algebraic and geometric concepts. Students seek the meaning of a problem and look for efficient ways to represent and solve it. They may check their thinking by asking themselves, “What is the most efficient way to solve the problem?”, “Does this make sense?”, and “Can I solve the problem in a different way?”.

What opportunities are you providing students to persevere with problem solving (and PBL)?

### Tip of the Week:

Bloom’s/DOK- Are we providing opportunities for our students to analyze, evaluate, create, and construct during math?

• Analyzeconstruct models, graphing information, comparing and contrasting values
• Evaluate– Prepare a list of criteria for solving, make a booklet that includes mathematical rules for solving and potential tools list

### Technology Integration Weekly Resources:

You could have students view the video, and ask them to then create their own video (or tell a partner if you do not have video equipment), to demonstrate with models and create their own “tutorial” with models.

By having them create their own tutorial, or presentation to a partner, they would then be using different multiple intelligences, and mathematical practices, to explain the “why” behind the mathematical computations.

How else can you take advantage of these videos as a learning opportunity for students?

### Mathematical Practices: Model with Mathematics

Model with mathematics includes:

• Understand this is a way to reason quantitatively and abstractly (able to decontextualize and contextualize)
• Are able to simplify a complex problem and identify important quantities to look at relationships
• Represent mathematics to describe a situation either with an equation or a diagram and interpret the results of a mathematical situation
• Ask themselves, “How can I represent this mathematically?”

In model with mathematics, students will:

• Apply prior knowledge to new problems and reflect
• Use representations to solve real life problems
• Apply formulas and equations where appropriate

Teachers will:

• Pose problems connected to previous concepts
• Provide a variety of real world contexts
• Use intentional representations
• Gives students opportunities to model with mathematics and describe the mathematical situation

Some questions to develop mathematical thinking could be:

• What number model could you construct to represent the problem?
• How would it help to create a diagram, graph, table …?
• What are some ways to visually represent …?

What opportunities are you providing students to analyze, evaluate, and create during math?

Double Dose Recommendations — Preteach the following:

• Relating measures, 2 days (#24‐#25). Look for science connections.
• Elapsed time, 3 days (#26‐28)

### Tip of the Week:

• Assessing/Higher Level Learning:  Are we having our students complete the Performance Based Assessments at the end of each Topic?
• Enrichment: In your teacher’s manual you will find ideas for enrichment under “Advanced/Gifted” on page 160D. There are two different ideas listed here.

### Technology Integration Weekly Highlight:

• Math in the Real World Project: The math project on page 161 in the Teacher’s Guide, connects to the real world by researching how many miles the top hiking trails are in the USA (the Appalachian Trail, the Pacific Crest Trail, and the Continental Divide Trail); then have the students pick one of the three trails and show the portion of the total trail in one state as a fraction. Then make a table that lists the state and the portion of the trail as a fraction.
• Students would use the computer for their research, and they could also use it for their reflection on the learning that took place in the above project. This would also be a great way to bring in the mathematical practice of attend to precision.
• Students could use Educreations on the iPad to narrate and show their thinking.
• On the netbooks or thin clients, students could create their table in Google Docs, then narrate their reflection by connecting Voice Comments (in Kaizena) to their document. Click here for instructions (see slide #14).

### Mathematical Practices:

The following comes from the ADE: 6.MP.6. Attend to precision. In grade 6, students continue to refine their mathematical communication skills by using clear and precise language in their discussions with others and in their own reasoning. Students use appropriate terminology when referring to rates, ratios, geometric figures, data displays, and components of expressions, equations or inequalities.

Some questions that can be asked for attending to precision includes:

• What mathematical terms apply in this situation?
• How did you know your solution was reasonable?
• What mathematical language…, definitions…, properties can you use to explain…?
• Explain how you might show that your solution answers the problem.

How do you use, and challenge students to use mathematics vocabulary precisely and consistently?

### Technology Integration Weekly Highlight:

Here are some websites with fractions for students to interact and engage with:

• Comparing Fractions — If you have students who need more experience with understanding fractions, this might be a place to build background. Have them use manipulatives while playing this game.
• Equivalent Fractions Game — If you have students who need more experience with understanding fractions, this might be a place to build background. Have them use manipulatives while playing this game.
• Equivalent Fractions Target Shoot — If you have students who need more experience with understanding fractions, this might be a place to build background. Have them use manipulatives while playing this game.

• LCM of three numbers —  This is an online worksheet. It gives immediate feedback to student about accuracy.
• Adding Mixed Numbers  —  This is an online worksheet. It gives immediate feedback to student about accuracy.

### Tip of the Week: Examples and Explanations

This tip comes from the ADE about finding the GCF and LCM: 6.NS.4

• What is the greatest common factor (GCF) of 24 and 36? How can you use factor lists or the prime factorizations to find the GCF?

Solution: 22 • 3 = 12. Students should be able to explain that both 24 and 36 have 2 factors of 2 and one factor of 3, thus 2 x 2 x 3 is the greatest common factor.)

• What is the least common multiple (LCM) of 12 and 8? How can you use multiple lists or the prime factorizations to find the LCM?

Solution: 23 • 3 = 24. Students should be able to explain that the least common multiple is the smallest number that is a multiple of 12 and a multiple of 8. To be a multiple of 12, a number must have 2 factors of 2 and one factor of 3 (2 x 2 x 3). To be a multiple of 8, a number must have 3 factors of 2 (2 x 2 x 2). Thus the least common multiple of 12 and 8 must have 3 factors of 2 and one factor of 3 ( 2 x 2 x 2 x 3).

• Rewrite 84 + 28 by using the distributive property. Have you divided by the largest common factor? How do you know?
• Given various pairs of addends using whole numbers from 1-100, students should be able to identify if the two numbers have a common factor. If they do, they identify the common factor and use the distributive property to rewrite the expression. They prove that they are correct by simplifying both expressions.
• 27 + 36 = 9 (3 + 4)

63 = 9 x 7

63 = 63

• 31 + 80

There are no common factors. I know that because 31 is a prime number, it only has 2 factors, 1 and 31. I know that 31 is not a factor of 80 because 2 x 31 is 62 and 3 x 31 is 93.

### Mathematical Practices:

6.MP.7. Look for and make use of structure.

Students routinely seek patterns or structures to model and solve problems. When students can rewrite 84 + 28 by using the distributive property, then answer if they divided by the largest common factor, then they are looking for and making use of structure.

Students will:

• look for, develop, and generalize relationships and patterns
• apply conjectures about patterns and properties to new situations

Teachers will:

• provide time for applying and discussing properties
• highlight different approaches for solving problems

What higher level questions will you ask during Topic 7 to help students look for and make use of structure?

Math Practice #4: Model with Mathematics

In grade 6, students model problem situations symbolically, graphically, tabularly, and contextually. Students form expressions, equations, or inequalities from real world contexts and connect symbolic and graphical representations. Students begin to explore covariance and represent two quantities simultaneously. Students use number lines to compare numbers and represent inequalities. They use measures of center and variability and data displays (i.e. box plots and histograms) to draw inferences about and make comparisons between data sets. Students need many opportunities to connect and explain the connections between the different representations. They should be able to use all of these representations as appropriate to a problem context.

If you asked students to represent a fraction in three different ways, how would that help them think about the mathematical practice of modeling with mathematics?

Have you used Galileo to identify the at risk students and students who need enrichment? (Cheri forwarded the directions to us via email with visuals). Here’s those directions again:

1. Go to the Dashboard.
2. See “Class Risk Level Summary” and “View Benchmark Results for Student Risk Levels.”
3. On Dashboard, it will show the risk level and students.
4. You can see the “Quiz Builder” to view areas of suggested reteaching or enrichment.

### Tip of the Week

• The Math Project for Topic 5 brings in real world examples and researching potentially active volcanoes in the USA. Based on their research, determine what fraction each is of the total number of active or potentially active volcanoes in the USA. Then have student determine which states have the most active or potentially active volcanoes. They can also rank them from greatest to least, and write their data in a table.
• I also liked the project mentioned in the ASCD article titled, “You Can’t Do That with a Worksheet.”

### Double Dose Recommendations

• Kim Sutton Math Routines (Number Line Workbook, Place Value, Math Drills to Thrill);
• Pre‐teach the following: Converting customary measures of length/weight/capacity, 5 days (#16‐#20) Look for science connections.

### Mathematical Practices

This tip comes from the ADE about making sense of problems and persevering in solving them (6.MP.7): Look for and make use of structure.

Students routinely seek patterns or structures to model and solve problems. For instance, students recognize patterns that exist in ratio tables recognizing both the additive and multiplicative properties. Students apply properties to generate equivalent expressions (i.e. 6 + 2x = 2 (3 + x) by distributive property) and solve equations (i.e. 2c + 3 = 15, 2c = 12 by subtraction property of equality; c=6 by division property of equality). Students compose and decompose two- and three-dimensional figures to solve real world problems involving area and volume.

Some questions that help students focus on structure are:

• What observations do you make about…?
• Do you recognize a rule or see an equation?
• Do you believe your rule will always work?
• How do you know your rule/equation will always work?
• What pattern or structure do you notice?
• Can sorting or grouping be used to solve?
• What are some other problems that are similar to this one?
• What ideas that we’ve learned before were useful in solving this problem?
• In what ways does this problem connect to other mathematical concepts?

What other questions could you ask to help students look for and make use of structure?
