Ask a child for double 7 and the answer often comes fast. Ask for 7 × 2 and the same child may start counting on fingers. This 3rd grade 2 times table worksheet joins the two ideas. It lists 18 facts in columns, labeled a to r, with numbers from 0 to 20. A girl on a skateboard rides along the top of a purple grid. Every answer is one of the even numbers, which gives a handy check. A second page gives the answer key.
