Explore the relationship between multiplication and division as scholars fill in these number sentences, each of which is missing a symbol. Is it a multiplication or division equation? There are 18 of these to start, all written horizontally. Encourage kids to notice patterns that could help them determine these more quickly. The next set of eight problems are written out in word-form sentences and are missing a dividend or factor (i.e. "I divide a number by 2 and the answer is 5. What is it?"). Finally, learners do 12 more missing-symbol problems. There are no remainders and all numbers are whole numbers.
