3rd grade math worksheets 15 sheets
Fifteen sheets for what grade 3 math works on in the Common Core: multiplication and division within 100, rounding to the nearest 10 and 100, adding and subtracting to 1,000, fractions, area and perimeter, and graphs in 2s and 5s. Print one, change it on its own page, or take the whole set as one PDF with the answer keys at the back.

How the sheets are chosen
Each sheet sits in the grade whose Common Core standard asks for its skill, and its card names the standard, as 3.OA.C.7 for multiplying and dividing within 100. A school that follows other standards may teach a skill a year earlier or later, so a child who finds a page easy can go on to the next grade’s, and one who needs more practice can go back a grade.
The facts to 10 × 10
By the end of grade 3 a child is expected to know all the products of two one-digit numbers from memory, and to divide within 100 by thinking of the multiplication: 40 ÷ 5 is 8 because 8 × 5 = 40. The multiplication and division sheets use factors from 1 to 10; the missing factor sheet asks the same facts as 8 × □ = 48.
The whole set
The set prints every sheet on this page once, in the order shown, after a contents page that lists them with their page numbers. The answer keys come together at the back, so you can print the sheets for the class and keep the keys apart. On its own page, each sheet makes new questions every time and can be changed; the set is one fixed copy, the same each time you download it.
