What we like about this lesson

Mathematically:

• Addresses standards 4.NF.A.2, 4.MD.A, 4.MD.A.2
• Allows students to see fraction equivalence with a large visual model
• Promotes coherence by highlighting prior knowledge and pointing to the mathematics that will be built from these ideas
• Encourages students to use appropriate tools strategically (MP.5) (see additional thoughts below)
• Requires students' use of precise grade-appropriate mathematical language (MP.6)
• Reinforces that fractional comparisons are valid only when referring to the same whole
• Uses fractions greater than 1 to support students’ understanding of fractions as numbers (e.g., 3/2, 5/3)

In the classroom:

• Captures student attention by using an engaging context
• Gives formal and informal opportunities for teachers to check for understanding
• Provides robust opportunities for students to discuss mathematical concepts; includes guiding questions for teachers to use to facilitate discussion
