# LESSON 22 HOMEWORK 2.7 EUREKA MATH

Strategies for Composing Tens and Hundreds Standard: Compare totals below to new groups below as written methods. Share and critique solution strategies for varied addition and subtraction problems within 1, Model 1 more and 1 less, 10 more and 10 less, and more and less when changing the hundreds place. Video Lesson 27 , Lesson Build, identify, and analyze two-dimensional shapes with specified attributes. Recognize the value of coins and count up to find their total value. Solve additions with up to four addends with totals within with and without two compositions of larger units. Tell time to the nearest five minutes. Interpret equal shares in composite shapes as halves, thirds, and fourths. Use math drawings to represent subtraction with up to two decompositions, relate drawings to the algorithm, and use addition to explain why the subtraction method works. Describe a whole by the number of equal parts including 2 halves, 3 thirds, and 4 fourths.

Add and subtract multiples of 10 including counting on to subtract.
