Vocabulary Sum: _________________________________
Difference:_____________________________ Product:_______________________________

Place Value Fill in the place value chart:
___, ___ ___ ___, ___ ___ ___ . ___ ___ ___ ___

Operations with Whole Numbers
Solve. = 8324 – 99 = 456 x 72 512 ÷ 8 =

Rule: Line the numbers up by their decimal points. Add zeros where necessary (after decimal point). Re-write Problem: = 0.73 – =

= 36.4 – 9.12 = = 5 – 0.03 = 88.88 – 1.259

Multiplying Decimals You DO NOT have to line the decimal points up!!!
Pretend there are no decimal points and multiply. At the end when you get your answer, count the number of decimal places and put the decimal point into your answer. 23.5 x 3.2 =

Multiplying Decimals (cont.)
Practice: 7.5 x 0.9 = 12.78 x 5.6 = 0.87 x 0.34 = 8 x 2.25 =
