Montana Math MT.5.NBT.6
The Standard
Flexibly, accurately, and efficiently find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division and illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

What This Standard Means
What Students Need to Do
- Students divide numbers up to four digits by two-digit numbers using place value and multiplication facts. They show their steps with an equation or area model and check by multiplying.
What Mastery Looks Like
- For 1,248 ÷ 24, a student can split 1,248 into 1,200 and 48, then find 50 + 2 = 52. They can label both parts of an area model and check that 52 × 24 = 1,248.
Common Misconceptions
- Students may treat 1,200 ÷ 24 as 5 rather than 50. Some stop after finding 50 groups and forget that the remaining 48 makes two more groups of 24.
How to Assess It
- Exit ticket: Solve 1,536 ÷ 32. Show two chunks in a labeled area model, then check your answer by multiplying.

Ways to Teach It
On half-centimeter grid paper, draw adjoining 24 × 50 and 24 × 2 rectangles, then label their combined area and total length.
Ask: Why can you split 1,248 ÷ 24 into 1,200 ÷ 24 and 48 ÷ 24? Explain with a sketch.
