5. Procedures/Methods-

A. Introduction-

(5 min)
1. Relate the upcoming activity to purchases multiples of the same item from a store, such as Mac's Market.

1. Model multiplying decimals as repeated addition of decimals using the red kangaroo problem (Activity 1)

2. Repeat the demonstration for Activity 2 on page 165.
 

C. Practice-

(10 - 15 min)
1. Have students make models to match problems 1 - 4 on page 165.
2. Monitor students as they color, ask questions about what they are doing. Have students say decimal numbers aloud.
*Early finishers may try numbers 9 - 12, finding the total cost of each purchase with or without using models.
3. Students will compare models with a neighbor.
 

D. Independent Practice-

(15 minutes)
1. Have students make models of problems 5 - 8.
*Early finishers may try numbers 9 - 12, finding the total cost of each purchase with or without using models.
 

E. Accommodations (Differentiated Instruction)-

1. Multiplication charts for students with accommodation.
2. One-on-one help with special education teacher fro students with accommodation.
3. Review of concepts of "tenths" and "hundredths" using the model.
 

F. Checking for understanding-

(15 minutes)
Assessment: Lesson quiz on page 165. Have students glue create models for these four problems.
 

G. Closure-

Explain to students that the next activity will involve making purchases of multiple items, and we will learn to multiply without using models.
 
6. Evaluation-
1. Groupings for the next day's follow-up activity will be based on the assessment.
