2 Use counters to make the arrays. How many counters in total
each time? (a) 3 × 2
(b) 4 × 2 (c) 5 × 2 Can you predict how many counters will be in a 10 × 2 array? Why will you also need 8 counters for a 2 × 4 array?
1 Draw number lines to show these repeated additions. Then write the multiplication sentences. (a) 2 + 2 + 2 + 2 + 2 + 2 + 2 = (b) 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = (c) 3 + 3 + 3 + 3 =
(d) 3 + 3 + 3 + 3 + 3 =
2 Leon wants to use counters to show each of these multiplication sentences as arrays. (a) Which of the arrays will have the same totals? Think first.
(b) Use counters to check.
