About these 3rd grade logic & problem solving worksheets

These 3rd grade logic and problem-solving worksheets stretch 3rd graders with real puzzles: a 4 × 4 logic grid, function tables, missing-digit addition and subtraction, 6 × 6 sudoku, place value riddles, shape algebra with multiplication, a multiples Venn diagram, word analogies, coding with loops, line-up logic, balance puzzles, growing patterns, bar model word problems, area puzzles and which-one-does-not-belong reasoning.

The math inside them follows the Common Core 3rd grade standards — patterns and function rules (3.OA.D.9), unknown numbers (3.OA.A.4), two-step problems (3.OA.D.8), place value (3.NBT.A.1) and area of combined rectangles (3.MD.C.7d) — and the puzzles build perseverance (MP.1), argument (MP.3) and repeated reasoning (MP.8).

All worksheet sets

How to get the most out of them

  1. 1

    Let your child explain their reasoning out loud on the logic grid and line-up puzzles. Saying “so nobody else can have carrots” is the skill.

  2. 2

    On function tables, ask for the rule in words first, then as a number sentence.

  3. 3

    Accept any well-argued answer on “Which One Does Not Belong?” — there is more than one right choice by design.

3rd Grade Logic & Problem Solving Worksheets — questions parents ask

Are these puzzles too hard for 3rd grade?
They are meant as a stretch. Each sheet starts with an easier item, and a child who finishes one puzzle carefully has done the work the sheet is for.
How do logic puzzles help with math?
Function tables, missing digits and bar models practise the same operations as drill sheets, but a child has to decide what to do first. That planning is the heart of problem solving.
