### LESSON 22 HOMEWORK 2.7 EUREKA MATH

Count the total value of ones, tens, and hundreds with place value disks. Use grid paper to create designs to develop spatial structuring. Pair objects and skip-count to relate to even numbers. Strategies for Composing a Ten Standard: Add and subtract multiples of 10 including counting on to subtract. Measure various objects using centimeter rulers and meter sticks.

Problem Solving with Categorical Data Standard: Partition circles and rectangles into equal parts, and describe those parts as halves, thirds, or fourths. Order numbers in different forms. Decompose to subtract from a ten when subtracting within 20 and apply to one-step word problems. Choose and explain solution strategies and record with a written addition method Video.

Connect measurement with physical units by using multiple copies eurekaa the same physical unit to measure. Apply and explain alternate methods for subtracting from multiples of and from numbers with zero in the tens place.

Model 1 more and 1 less, 10 more and 10 less, and more and less when changing the hundreds place. Represent equal groups with tape diagrams, and relate to repeated addition. Student Explanations of Written Methods Standard: Creating an Inch Ruler Standard: Recognize that equal parts of an identical rectangle can have different shapes. Interpret equal shares in composite shapes as halves, thirds, and fourths.
