Essential Questions Example: A gumball costs $0.22. How much do 5 gumballs cost? Activator What strategies can I use to multiply and divide decimals efficiently? How do I use an area model to help me Whole group multiply decimals? How do I use a model to help me divide decimals? Students thinking: I have ten whole columns shaded and 10 individual boxes shaded. The 10 columns equal 1 whole. The Base Ten Activity pg. 28 10 individual boxes equal 10 hundredths or 1 tenth. My pg. 49 answer is $1.10. pg. 53 Example: An area model can be useful for illustrating pg. 45 products. (no models) pg. 41 See page 1 pg. 59 Continued on page 2 Continued Whole Group Continued from page 1 (Models and Standard Algorithm) Students should be able to describe the partial products displayed by the area model. For example, (Printable) 3/10 times 4/10 is 12/100
