All word problems are dynamic (in other words, they regenerate a new problem each time you open them or click refresh on your browser).
The words in the particular problem will not change but the numbers will.
Children who struggle converting a word problem into a math equation will find it reassuring (confidence builder) to revisit the same verbal clues with different numbers, so consider printing a couple regenerations of each problem.
In a classroom setting you can provide a problem to partners or a group of students to solve together and then provide a regeneration of the same problem for the children to do solo.
It is usually a good idea to ensure students already have a strategy or two in place to complete the math operations involved in a particular question.
For example, students may need a way to figure out what 7 × 8 is or have previously memorized the answer before you give them a word problem that involves finding the answer to 7 × 8.
The first two sheets involve drawing out different amounts in groups and solving simple problems which do not require any reasoning skills.
Sheets 3 to 5 involve understanding and working out division word problems that require a little more reasoning and thinking about.
By the end of 3rd grade, most children should be able to add and subtract numbers to 100 mentally, know their multiplication tables up to 10 x 10, and make simple estimates.
They are able to multiply and divide at a basic level, and can solve multiplication and division problems.
