### Double Dose Recommendations:

• Kim Sutton math routines.
• Pre-teach the following: Area, 5 days (#34-38)

### Tip of the Week:

• The Topic Opener/STEM Project on page 201 not only brings in math in the context of the real world, but it also requires informational text reading and researching.
• New York City Department of Education created a performance task, Share My Candy, for dividing fractions by fractions, which includes a rubric.

### Technology Integration Resources:

Videos:

Online & interactive practice, that progressively gets more difficult from IXL:

### Mathematical Practices:

MP6- Attend to Precision

• Communicate precisely to others
• Use clear definitions in discussion with others and in their own reasoning
• State the meaning of symbols they choose (equal sign)
• Specific with units of measure, labeling, and quantities
• Calculate accurately and efficiently

Question/Practice Stems

• Why do you believe that to be true?
• How did you reach your conclusion?
