Multiplication:By Kena

Learning Intention-W.A.L.T-multiply by counting up to 100. and repeated using addition.
Success Criteria:I know I am successful when I multiply numbers using skip counting,doubles and repeated addition.

Problems:  

1. How many marbles are there altogether?

Two children had 10 marbles each=20
I know it's 20 because I skip count by two's 2,4,6,8,10,12,14,16,18,20
10+10=20
10 x 2=20

2. Poppy,Sam, Millee had 5 marbles each.=
How many marbles do they have altogether= 15
I know the answer is 15 because I skip counted by five's.
5,10,15
Another way is repeated addition=  5+5+5=15
I also used multiplication=  5 x 3 =15
