Cooke's Math Resources

The operation of addition is based on the counting of objects. This introduction to the addition of mixed numbers uses pictures of halves, thirds, sixths, and eighths to first engage students in counting by halves, thirds, etc. so that finding sums will feel intuitive.

This 16-page packet has math facts review at the top of each page and uses the same divisor on each page. Because the dividends are presented in increasing order, students can begin to see a pattern to their quotients. The pages in which students practice with 2-digit divisors use the same divisor on each page, and they begin by completing sequences made up of multiples of that divisor. Through the use of careful sequencing and meaningful repetition, students begin to experience the logic of mul

Some students struggle with the concept of long division. Using the same divisor on a page makes it possible for students to recognize a pattern to their quotients as they divide increasingly large dividends by the same divisor. These sheets are presented in a controlled fact format so that students are not struggling to recall many different facts while also learning the division algorithm.

Some children find subtraction with renaming (regrouping) difficult because they struggle to recall number facts. These worksheets are presented in a controlled fact format so that the student can practice the skill of multidigit subtraction while at the same time practicing a single family of number facts.
