### Target 1​

###### Lesson Type:

New

Number Operation

:

Computation

Solve multi-step problems within 100 (addition, subtraction, multiplication, and division).

###### 1:

Solve problems that have more than one operation.

###### 2:

Understand that the presence of parenthesis in an arithmetic equation signals for this part of the problem to be solved first.

###### 3:

Understand when solving a problem that has both addition and subtraction operations that solving starts on the left and continues to the right.

1st

###### Vocabulary:

Addition, Subtraction, Multiplication, Division, Parenthesis, PEMDAS, Inverse

Activities:

Students were introduced to PEMDAS and its rules. Students worked on practice problems that have more than one operation.    ### Home Exploration

### Target 2

:

###### 1:

Estimate quantities and use one-to-one correspondence to check the accuracy of the estimate.

###### 2:

Develop a strategy for estimating quantities (i.e., developing a unit of measurement for estimating – if this is what 10 units looks like this must be close to 40 units).

###### 3:

Understand that rounding and estimation are a way to quickly check the accuracy of computations.

###### 4:

Understand that you can use estimation when an exact answer is not needed.

1st

###### Vocabulary:

Estimate, Rounding

Activities:

Students were introduced to the rules of estimating a number. Students were given a few numbers which they estimated. Students worked on addition and subtraction problems using estimation.    ### Home Exploration
