Use manipulatives to represent the composition of 10 ones as 1 ten with two-digit addends. Recognize that equal parts of an identical rectangle can have different shapes. Strategies for Decomposing a Ten Standard: Decompose to subtract from a ten when subtracting within and apply to one-step word problems. Solve two-step word problems within Represent arrays and distinguish rows and columns using math drawings. Creating an Inch Ruler Standard:

Measure to compare the differences in lengths using inches, feet, and yards. Subtract multiples of and some tens within 1, Use manipulatives to represent additions with two compositions. Write base ten numbers in expanded form. Represent two-digit sums and differences involving length by using the ruler as a number line. Relate manipulative representations to a written method. Solve two-step word problems within
