1. Exponents and Multiplication
Use mental math to complete the table.
1 roll = 50 dimes
(think 50 dimes per roll X 20 rolls =
(5 X 2) X (10 X 10)
Rolls
Dimes 10x10’’ (complete table on next slide)

Did You Know???
Blood is necessary for all human life. It contains red blood cells and white blood cells that nourish and cleanse the body, and platelets that stop bleeding. The average adult has about 5 liters of blood.
Use Patterns and Mental math to solve the following!!!

12. Exponents and Multiplication
The human body has about 30 times as many platelets as white blood cells. A small sample of blood has 8 X 10’’’ white blood cells. About how many platelets are in the sample?

13. Exponents and Multiplication
Basophils and monocytes are types of white blood cells. A blood sample has about 5 times as many monocytes as basophils. If there are 60 basophils in the sample, about how many monocytes are there?

14. Exponents and Multiplication
Lymphocytes and eosinophils are types of white blood cells. A blood sample has about 10 times as many lymphocytes as eosinophils. If there are 2 X 10’’ eosinophils in the sample, about how many lymphocytes are there?

15. Exponents and Multiplication
An average person has 6 X 10’’ times as many red blood cells as white blood cells. A small sample of blood has 7 X 10’’’ white blood cells. About how many red blood cells are in the sample?
