Description
Students multiply and divide decimals by powers of 10 in this festive winter math activity that doubles as classroom décor. Students multiply decimals by 0.01, 0.1, 10, 100, 1000 and divide decimals by 10, 100 and 1000.
100 and 1000 are expressed as 10^2 and 10^3 in ornaments #25-#44. Ornaments #45-#50 ask students to multiply decimals by negative powers of 10. These last 6 ornaments could be given as an extension or as an added challenge.
Problems type examples:
3.24 x 0.1 = (12 ornaments)
12.03 ÷ 100 = (12 ornaments)
8.5 x 10^3 = (10 ornaments)
21.59 ÷ 10^2 = (10 ornaments)
1.98 x 10^-2 = (6 ornaments)
There are 50 ornaments in this activity, along with 4 "blank" ornaments where you can hand write your own multiplication and division problems. Also included is an optional student answer sheet and an answer key.
