Evaluation for 5.4d
Materials include embedded guidance to facilitate mathematical conversations allowing students to hear, refine, and use math language with peers.
The materials include embedded guidance to facilitate mathematical conversations, allowing students to hear, refine, and use math language with peers in "Concept Mini Lessons." For example, in grade 2, "Subtract: Subtract Within 1,000 by Using Mental Strategies," students review the use of a number line to move backwards to subtract. The materials state, "We can take away hundreds and tens by using backward hops on a number line. When there are not enough tens from which to subtract, we can decompose the part to get to a benchmark number, such as a hundred, and then subtract some more." Students are then invited to turn and talk with a partner about how they can use the number line to help them subtract like units, using mathematical language from the lesson.The materials include "Teacher Tips" and "Language Support" in the "Concept Mini Lessons" to facilitate mathematical conversations. For example, in grade 2, "Addition: Add Within 1,000 by Using Mental Strategies," the "Teacher Tip" offers tips to support students in understanding the concept by using a number line. The materials state, "Some students may benefit from using open number lines and hops to show how the two expressions are equal." The "Language Support" offers support for the inclusion of mathematical terms. The materials state, "Consider providing a word bank to support student discussion. Include words and phrases such asefficient,make a ten,benchmark number,decompose,addends, andtotal."In the "Application" section, students hear, refine, and use math language with peers. For example, in grade 2, "Place Value: Compose, Decompose, and Represent Numbers to 1,200," students work with a partner to solve a multi-part task involving composing, decomposing, and representing numbers to 1,200. Students use contextual information to support their understanding and apply critical thinking, along with mathematical language, to solve three related problems.
