How can we use the concept:
A multiplication table is an aid that lists the multiplication tables for numbers 0 - 12. When viewing the multiplication facts for a particular number on the multiplication table, it becomes clear that we are actually adding a group of that number as we proceed down the table.
Ex.,
2 x 0 = 0 (no groups of 2 = 0)
2 x 1 = 2 (one group of 2 = 2)
2 x 2 = 4 (two groups of 2 = 2 + 2 = 4)
2 x 3 = 6 (three groups of 2 = 2 + 2 + 2 = 6)
2 x 4 = 8 (four groups of 2 = 2 + 2 + 2 + 2 = 8)
2 x 5 = 10 (five groups of 2 = 2 + 2 + 2 + 2 + 2 = 10)
2 x 6 = 12 (six groups of 2 = 2 + 2 + 2 + 2 + 2 + 2 = 12)
2 x 7 = 14 (seven groups of 2 = 2 + 2 + 2 + 2 + 2 + 2 + 2 = 14)
2 x 8 = 16 (eight groups of 2 = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 16)
2 x 9 = 18 (nine groups of 2 = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 18)
2 x 10 = 20 (ten groups of 2 = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 20)
2 x 11 = 22 (eleven groups of 2 = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 22)
2 x 12 = 24 (twelve groups of 2 = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 24)
In this example, we are adding a group of 2 for each multiplication fact. Essentially, we can count by 2’s to find the answer (product) to a multiplication fact of 2.
