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.

Tell time to the nearest five minutes. Add multiples of and some tens within 1, Use scissors to partition a rectangle into same-size squares, and compose arrays with the squares. Relate the square to the cube, and describe the cube based on attributes. Strategies for Adding and Subtracting Within 1, Standard: Count the total value of ones, tens, and hundreds with place value disks.

Decompose to subtract from a ten when subtracting within 20 and apply to one-step word problems. Subtract from and from numbers with zeros in the tens place.

Video Lesson 16Lesson Use number bonds to break apart three-digit minuends and subtract from the hundred. Problem Solving with Coins and Bills Standard: Apply and explain alternate methods for subtracting eurek multiples of and from numbers with zero in the tens place. Write base ten three-digit numbers in unit form; show the value of each digit. Model and use language to tell about 1 more and 1 less, 10 more and 10 less, and more and less.

Represent arrays and distinguish rows and columns using math drawings. Use math drawings to represent additions with up to two compositions and relate drawings to a written method.
