Target 1​

Lesson Type:

Continuation

Number Operation

:

Operational Relationships

Use properties of operations as strategies for adding and subtracting.

Supporting targets:
1:

Identify the Commutative Property of Addition.

2:

Understand that changing the order of addends, does not change the sum.

3:

Understand the inverse relationship between addition and subtraction.

Grade:

2nd

Vocabulary:

Inverse Operations, Fact Family

Activities:

We reviewed commutative property. You can switch the order of the numbers, but the answer will be the same. We also reviewed inverse operations. The numbers on dominos represented 2 addends. Students used triangles to complete the fact family. The addends were written on the 2 bottom angles, and sum was written at the top. Students used the same 3 numbers to create subtraction sentences. [5 + 6 = 11, 6 + 5 = 11, 11 - 5 = 6, 11 - 6 = 5] We also discusssed how you can switch the order of the numbers to solve for an unknown number. [11 - __ = 6, so 11 - 6 = __. The unknown number is 5.]

Congruent

Activities:

The term "congruent" was introduced. Items that are congruent are the same shape and size. We watched a short video about similar and congruent shapes to help build our understanding of congruency. Then students created congruent 3x3 grids and identified the shape that was congruent to the given figure.
