4th grade math · Unit 3: Division

What to do with the remainder

What this lesson shows

Four stories, four answers: add one more van, drop it, keep only the leftover, or split it.

The worked example

The lesson works this one step by step: 26 ÷ 4. Then your kid tries one like it on paper.

The steps

  1. Add one more
  2. Drop it
  3. Only the remainder
  4. Split it

Helping at home

Divide first, then read the question again and ask what the story needs: one more, drop it, only the remainder, or split it. Say why out loud.

Standards

  • Common Core 4.OA.A.3
    Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
  • Common Core 5.NF.B.3
    Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?
