### EUREKA MATH LESSON 2 HOMEWORK 2.3

Decompose to subtract from a ten when subtracting within and apply to one-step word problems. 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. Pair objects and skip-count to relate to even numbers. Combine shapes to create a composite shape; create a new shape from composite shapes. Draw a line plot to represent the measurement data; relate the measurement scale to the number line.

Apply conceptual understanding of measurement by solving two-step word problems Video. Identify unknown numbers on a number line diagram by using the distance between numbers and reference points. Use manipulatives to represent additions with two compositions. Use math drawings to represent the composition and relate drawings to a written method. Write, read, and relate base ten numbers in all forms. Try the given examples, or type in your own problem and check your answer with the step-by-step explanations. Use square tiles to decompose a rectangle.

Describe two-dimensional shapes based on attributes. Order numbers in different forms.
