Refer to the notes for pages 6 and 12.
Encourage students to list facts they do not know and attempt to learn them. It is beneficial to focus on pattern (see pages 8 and 9 of Basic Facts). For example, if a student knows 8 x 8 = 64 but does not know 9 x 8 = 72, provide the student with a 10 x 10 array of objects and two masking cards:
Ask the student to use the masking cards to show 8 x 8.
Then ask the student questions such as:
“How many is that altogether?”
“How many more will you need to uncover to show 9 x 8?” (another row/column of eight)
“How much will that be?” (64 + 8 is 72)
You could also link this unknown fact to 10 x 8 = 80 and ask “How much less is 9 x 8?” Students may wish to make flash cards of their unknown facts with the facts on one side and the answers on the other. Students may self-test or work with a partner.
Answers are provided on the page as the bottom line of the table, shown in orange.
