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.

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. Oneonone 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 followup activity will be based
on the assessment.
