This is the final math assessment for multiplication skills up to 10, with this unit focusing on multiplying by 8 and 9. Students begin by extending skip-counting number patterns (8, 16, 24 and 9, 18, 27) to see how multiplication grows additively. Then apply those patterns to a variety of tasks including matching equivalent expressions, choosing the correct product from multiple-choice bubbles, drawing or writing arrays, and filling in missing factors in equations such as ___ x 8 = 40. The pages give repeated practice with both vertical and horizontal formats, relate repeated addition to multiplication, and require students to reason about inverse relationships (finding the factor that makes 27 when multiplied by 9).
