- Question 1easyMultiplication
What is 6 × 7?
Show answer and worked solution
Answer: 42
Six groups of seven. Count up by 7: 7, 14, 21, 28, 35, 42.
- Question 2easyMultiplication
What is 9 × 4?
Show answer and worked solution
Answer: 36
9 × 4 is the same as 10 × 4 minus one 4: 40 − 4 = 36.
- Question 3easyDivision
What is 45 ÷ 5?
Show answer and worked solution
Answer: 9
Ask how many 5s make 45. Since 5 × 9 = 45, the answer is 9.
- Question 4easyFractions
Which is larger, 1/3 or 1/5?
Show answer and worked solution
Answer: 1/3
The same whole split into 3 pieces gives bigger pieces than splitting it into 5, so 1/3 > 1/5.
- Question 5easyRounding
Round 268 to the nearest 10.
Show answer and worked solution
Answer: 270
The ones digit is 8, which is 5 or more, so round the tens up from 60 to 70.
- Question 6mediumArea and perimeter
A rectangle is 7 cm long and 4 cm wide. What is its area?
Show answer and worked solution
Answer: 28 square cm
Area = length × width = 7 × 4 = 28 square centimetres.
- Question 7mediumArea and perimeter
What is the perimeter of a rectangle 7 cm by 4 cm?
Show answer and worked solution
Answer: 22 cm
Perimeter = 2 × (7 + 4) = 2 × 11 = 22 cm. Add all four sides.
- Question 8mediumDivision
A teacher shares 56 pencils equally between 8 tables. How many per table?
Show answer and worked solution
Answer: 7 pencils
56 ÷ 8 = 7 because 8 × 7 = 56.
- Question 9hardWord problems
Maya buys 4 packs of 6 stickers and gives 9 away. How many are left?
Show answer and worked solution
Answer: 15 stickers
First multiply: 4 × 6 = 24. Then subtract: 24 − 9 = 15. Two steps, in that order.
- Question 10hardFractions
A pizza is cut into 8 equal slices and 3 are eaten. What fraction is left?
Show answer and worked solution
Answer: 5/8
8 − 3 = 5 slices remain out of 8, so 5/8 of the pizza is left.

What Grade 3 students are expected to master
The single biggest shift in third grade is that multiplication and division become the organising idea for almost everything else. Students are expected to know their facts within 100 fluently enough that a fact does not slow down a two-step problem. If a child is still counting up by sevens on their fingers in April, the fact work is not finished, no matter how well they do on the rest of the curriculum.
The second shift is fractions. Grade 3 introduces fractions as numbers on a number line rather than as pictures of pizza. This is where a lot of later fraction confusion starts: a student who only ever sees 3/4 as three shaded quarters of a circle will struggle in Grade 4 when asked to place 3/4 between 0 and 1. Practise both representations.
How to use these worksheets in a Grade 3 class
Start with the easy set as a warm-up and watch the clock rather than the answers. Third graders who take longer than about five seconds per multiplication fact are recalling by calculation, not memory, and they will run out of working memory on the two-step problems later in the year. That is a fluency issue and needs short daily practice, not a longer worksheet.
The medium and hard questions are deliberately mixed across topics, because tests are mixed. Students who can do a page of twenty multiplication questions but freeze when a multiplication question appears next to a fraction question have learned the page, not the skill. Interleaving is uncomfortable and it is what makes the learning stick.
