Reflection: Connection to Prior Knowledge Criss Cross Comparison - Section 4: Student Practice


While conferring with students, I tried to connect new learning to prior knowledge to provide further support. Here, Comparing Numerators, a student needed support with remembering how to compare two fractions with common denominators. I used a simpler model (1/2 __ 1/4) to explain this further. Once the student connected the criss-cross method with prior knowledge, she was ready to go!

Criss Cross Comparison

Unit 10: Fractions
Lesson 9 of 16

Objective: SWBAT compare fractions using the criss-cross method.

Big Idea: Students will begin by exploring a variety of strategies to compare fractions, but will focus mostly on the criss-cross method, a fun and quick way to compare fractions with unlike denominators.
