Learning Games for 4th Graders: Long Division and Fractions That Match

Fourth grade is the first year where a maths topic can fail for a reason that started two years earlier. Long division needs multiplication facts, subtraction with regrouping and place value, all at once, in a loop. When a fourth grader "can't do long division", the broken part is almost never the division.

Long division, diagnosed. Watch one problem. If they hesitate at "how many 7s in 45", it is the tables. If they get the digit right but subtract wrongly, it is regrouping. If they lose track of which column they are in, it is place value or simply handwriting. Fix the layer that is actually broken.

Equivalent fractions. The rule "multiply top and bottom by the same number" is easy to say and easy to apply mechanically without understanding it. The check that matters: can the child say why 3/4 and 9/12 are the same amount? If not, comparing and adding fractions will collapse next year.

Angles get measured now, not just named. A protractor has two scales and children read the wrong one constantly. The fix is to estimate first — "is this bigger or smaller than a right angle?" — and only then read the number.

Multi-digit multiplication is really the distributive law in disguise: 23 × 4 is 20×4 plus 3×4. Children who see that can check their own answers; children who only follow the algorithm cannot.

Beyond maths. Fourth graders can handle genuine science content — circuits, forces, food webs, the water cycle — and genuine reading comprehension, where the answer is in the text but not in the words of the question.
