#### Indicator

• 1. Apply number relationships
##### Objective
1. Build and describe models of even and odd numbers using concrete materials, and discuss the models

### Topic

C. Number Computation

#### Indicator

• 1. Analyze number relations and compute
##### Objectives
1. Demonstrate proficiency with addition and subtraction basic facts using a variety of strategies
2. Add no more than 3 whole number addends with no more than 2 digits in each addend and a sum of no more than 100
3. Subtract whole numbers with no more than 2 digits in the minuend or the subtrahend
4. Solve word problems based on addition or subtraction situations
5. Write word problems for addition and subtraction situations
6. Add and subtract money amounts up to \$1
7. Apply the concept of inverse operations to addition and subtraction
8. Build equal groups to model multiplication
9. Build groups that share equally for division

#### Indicator

##### Objective
1. Determine the reasonableness of sums and differences

Note: Highlighted assessment limits will be tested in the no calculator section of MSA. In the assessment limit, (0-10) or (-10 to 10) means all numbers in the problem or the answer will fall within the range of 0 to 10 (including endpoints) or -10 to 10 (including endpoints), respectively. All content standards are tested in MSA but not all objectives. Objectives that have an assessment limit are tested on MSA. Objectives without an assessment limit are not tested on MSA.
