A free printable 3rd grade summer math review with 40 mixed problems, visual geometry practice, and a complete answer key for students entering 4th grade.
Third grade is where multiplication, division, fractions, and multi-digit thinking begin to work together. This packet revisits those ideas in short, varied sets so students practice choosing an operation instead of repeating one procedure for a whole page.
Try one section at a time on different days. If a student misses two problems in one section, pause to model that skill with drawings or objects before assigning more practice.
Every question below appears in the printable packet. Students should show their work and simplify answers unless directed otherwise.
Compute accurately and check whether an answer is reasonable.
Use facts, equal groups, and the relationship between multiplication and division.
Interpret fractions as equal parts and compare simple fractions.
Read, decompose, compare, and round whole numbers.
Work with time, length, and perimeter in familiar settings.
Recognize attributes of shapes and find area with unit squares.
Represent one- and two-step situations with equations.
Explain patterns and apply more than one idea.
Open-ended explanations may use different wording while showing the same reasoning.

37. 80; double each number
38. 852 - 258 = 594
39. No. With the same numerator, eighths are smaller pieces, so 3/4 > 3/8
40. 4 units; 6 + 6 uses 12 units, leaving 8 units for two equal sides
