Target 1​

Lesson Type:

Continuation

Number Operation

:

Computation

Divide within 100.

Supporting targets:
1:

Understand that dividing numbers makes numbers smaller.

2:

Understand that division represents taking a quantity and determining how many equal groups of objects can be made.

3:

Understand that division can be represented with repeated subtraction.

Vocabulary:

Division, "Fair Share," Repeated Subtraction

Activities:

We continued division. Students practiced dividing cubes into equal groups. Ex. 28/4=7 Students could "fair share" the cubes to make 4 equal groups of 7 cubes OR put 4 cubes in each group to make 7 groups. Students drew pictures to represent division. We also practiced repeated subtraction as a strategy to divide. Students could use a number line to help with counting back. Ex. 28-4=24, 24-4=20, 20-4=16, 16-4=12, 12-4=8, 8-4=4, 4-4=0 *4 was subtracted from 28, 7 times.

Algebra
Sequence
Use arithmetic to define a sequence and calculate the next unit in a series.

:

Supporting targets:
1:

Study a given arithmetic sequence to determine what rule explains the sequence (i.e., 2-4-6-8-10…each number is the sequence gets bigger by 2).

2:

Write an arithmetic rule to explain a given sequence.

Vocabulary:

Pattern, Rule

Activities:

Students looked at a sequence of numbers and determined the pattern. After identifying the rule, ex. add 4, students determined the next few numbers in the sequence. Students used a number line to help with counting on.
