Decompose to subtract from a ten when subtracting within and apply to one-step word problems. Partition circles and rectangles into equal parts, and describe those parts as halves, thirds, or fourths. Count the total value of ones, tens, and hundreds with place value disks. Count up to 1, on the place value chart. Use math drawings to represent subtraction with up to two decompositions and relate drawings to a written method.

Represent subtraction with and without the decomposition when there is a three-digit minuend. Use math drawings to represent additions with up to two compositions and relate drawings to a written method. Represent two-digit sums and differences involving length by using the ruler as a number line. Interpret equal shares in composite shapes as halves, thirds, and fourths. Connect measurement with physical units by using iteration with an inch tile to measure. Compare totals below to new groups below as written methods.

Describe a whole by the number of equal parts including 2 halves, 3 thirds, and 4 fourths.
