Recognize the value of coins and count up to find their total value. Pair objects and skip-count to relate to even numbers. Add and subtract multiples of 10 including counting on to subtract. Video Lesson 16 , Lesson Strategies for Decomposing Tens and Hundreds Standard: Use math drawings to represent the composition when adding a two-digit to a three-digit addend.
Write, read, and relate base ten numbers in all forms. Use the associative property to make a hundred in one addend. Count the total value of ones, tens, and hundreds with place value disks. Measure and compare lengths using centimeters and meters. Use math drawings to represent subtraction with up to two decompositions and relate drawings to a written method. Use math drawings to represent equal groups, and relate to repeated addition. Video Lesson 3 , Lesson 4:
Apply concepts to create inch rulers; measure lengths using inch rulers. Count up and down between and using ones and tens. These Lesson Plans and Worksheets are divided into eight modules.
Relate manipulative representations to the addition algorithm. Relate manipulative representations to the subtraction algorithm, and use addition to explain why the subtraction method works. Solve word problems involving the total value of a group of bills.
Video Lesson 7Lesson 8: Solve word problems involving addition of equal groups in rows and columns. Pair objects and skip-count to relate to even numbers. Sums and Differences Within Standard: Problem Solving with Coins and Bills Standard: Formation of Equal Groups Standard: Use square tiles to decompose a rectangle.
Model 1 more and 1 less, 10 more and 10 less, and more and less when changing the hundreds place. Video Lesson 9Lesson Video Lesson 16Lesson Investigate the pattern of even numbers: Make number bonds through ten with a subtraction focus and apply to one-step word problems. Use mental strategies to relate compositions of 10 tens as 1 hundred to 10 ones as 1 ten. Relate doubles to even numbers, and write number sentences to express the sums.
