Objectives Students will find the product of a single-digit number and a double-digit number. Students will understand how rearranging the numerals affects the product of a single-digit number and a double-digit number. Materials Needed Baseball number cards template Multiplication Mania reproducible Scissors Introduction Write the problems 23 x 9 and 93 x 2 on the board. Ask students, “Do you notice anything similar about these two problems? Yes, they both use the same numerals but in different places.” Invite students to make a guess as to which product will be greater. Give them time to find the answers (23 x 9 = 207 and 93 x 2 = 186). Then ask students if they can think of different ways to arrange the three numerals so that the product would be greater than 207 or less than 186. Invite students to use a pencil and paper to work out some possible problems and their answers (such as 39 x 2 = 78, 29 x 3 = 87, 92 x 3 = 276 and 32 x 9 = 288).
