## Tips, Mathematical Practices, and Ideas about Solving Proportions

on February 13, 2014

### Standards

Topic 13 focuses mainly on Ratios and Proportional Relationships (RP) 3, 3a, and 3b:

• CCSS.Math.Content.6.RP.A.3 Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
• CCSS.Math.Content.6.RP.A.3a Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
• CCSS.Math.Content.6.RP.A.3b Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?

### Double Dose Recommendation:

Pre-teach the following:

• Reading Frequency tables and histograms, 2 days (#71-2)
• Stem and Leaf Plots, 3 days (#73-35)

### Tip of the Week:

One highlight of my walk-through at FPES a few weeks ago was seeing an awesome cumulative review game in several classes. Math Instructional Coach, Kathleen Donlan, engaged classes in this powerful collaborative group math game. She originally got the idea from a math competition she went to years ago, and has tailored the game to fit the classes with the standards they’ve learned so far.

### Math Practices

The Teaching Channel created a great video about including math practices and explicitly in daily instruction.

How do you include the math practices daily?

If you have used Kathleen Donlan’s review game, what insight can you share with others?

1. I also wanted to recommend that you read this post by Principal Heidi Golemon on ratios and DOK.

What we do for the rounds game, in case you were not at the meeting, is we start with round 1, students answer the 6 questions in a group of 4. It is a competition, When and if they have all the problems right for round 1 done they give you round 1 and get round 2 and so on through round 3. The first time we did it took about an hour I will let you know next week if we did it faster this time. I give the 1st team to finish 2 pieces of “fruit” and every team that participates and or finishes gets one piece of fruit.

NOTE: (You will need to carry the key for each rounds questions and this is where DOK 3&4 come in if something is wrong you tell them where to go back to and ask them to figure out what they did wrong.)

Make each round a different color so you can see where each group is at, and when you give them their strips of paper for each round make them keep track of their paper clip and have them clip the first round back for you before they get the next round from you. It makes it easier to keep track of the little slips.

Prepare for it to be loud and wear a comfortable pair of shoes that day. Enjoy and let there be laughter, joy, and lots of DOK 3 & 4 in your math classes this week & next week.

I found this video on you tube using a tic tac toe board to set up proportions and thought this was a cool way of doing it…..
