What’s on grade 3 math

We couldn’t confirm the NM-MSSA’s own reporting categories for grade 3 on the state’s pages, so the practice set groups its questions by topic:

Operations and Algebraic Thinking

  • Multiplication and division facts within 100
  • Finding the unknown number in a multiplication or division equation
  • Word problems with equal groups and arrays
  • Word problems that share or group things equally
  • Using the properties of multiplication to find products
  • Two-step word problems with all four operations
  • Patterns in the multiplication table
  • Money: earning, saving and spending

Number and Operations in Base Ten

  • Rounding to the nearest 10 or 100
  • Adding and subtracting within 1,000
  • Word problems with adding and subtracting
  • Multiplying by multiples of 10

Number and Operations: Fractions

  • Fractions as equal parts of a whole
  • Fractions on a number line
  • Comparing fractions and finding equal fractions

Measurement and Data

  • Time to the minute and elapsed time
  • Word problems with grams, kilograms and liters
  • Reading scaled picture graphs and bar graphs
  • Area by counting unit squares and by multiplying
  • Perimeter of rectangles and other shapes

Geometry

  • Kinds of quadrilaterals, and what their sides and angles have in common
  • The NM-MSSA checks the New Mexico Common Core State Standards.
  • The real grade 3 test: Two sessions of about 60 minutes each (no calculator, then calculator)
  • Calculators: Math has a no-calculator session and a calculator session.

How to help at home

  1. Do one set, then talk

    After a set, look at the ones they missed together. Ask how they got their answer before saying what the right one is.

  2. Little and often

    A short set a few times a week does more than a long session the week before.

  3. Use real life

    Prices at the store, recipes, distances and times on a trip: grade-level math is everywhere.

  4. Keep it calm

    The test checks how the year went. A good night’s sleep helps more than cramming.
