Students will describe, represent, or apply numbers or their relationships or will estimate or compute using mental strategies, paper/pencil or technology.

Topic

A. Knowledge of Number and Place Value

Indicator

Objectives
  1. Use concrete materials to compose and decompose quantities up to 100
  2. List multiple representations for a number
  3. Develop a sense of the size of a number in relation to other numbers
  4. Use the numbers of 10, 50, and 100 as anchors in relationship to other numbers
  5. Read, write, and represent whole numbers using models, symbols, and words through 1000
  6. Express whole numbers up to 999 using expanded form
  7. Identify the place value of a digit in whole numbers up to 999
  8. Compare and order whole numbers up to 999 using words and relational symbols ( >, <, =)
  9. Estimate quantities up to 100 using a reference point such as 10 and the terminology "about"
  10. Count forward by 2s, 5s, and 10s starting with numbers other than one
  11. Count backward by 2s, 5s, and 10s from a multiple of that number
  12. Use ordinal numbers to indicate position up to thirty-first

Indicator

  • 2. Apply knowledge of fractions
Objectives
  1. Read, write, and represent fractions as parts of a single region using symbols or models with denominators of 2, 3, or 4
  2. Read, write, and represent halves or fourths as parts of a set using symbols, words, and models

Indicator

  • 3. Apply knowledge of money
Objectives
  1. Determine the value of a given set of mixed currency up to $10
  2. Represent money amounts up to $10
  3. Compare the value of 2 sets of mixed currency up to $10

Topic

B. Number Theory

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.
