A loop can sit inside another loop. The inside loop runs fully each round.
A loop can sit inside another loop, like a smaller doll inside a bigger doll.
The inside loop runs all the way through every time the outside loop goes round.
To count the total, multiply: the outside number times the inside number.
A step after the inside loop runs once for each round of the outside loop.
These are some of the questions on the sets. The printable sheets have more and an answer key.
10. 2 x 5 = 10.
12. 4 x 3 = 12.
5. Once for each round of the outside loop.
Multiply. The inside loop runs fully each round.
15. 3 x 5 = 15.
Set the table with a loop inside a loop. The outside loop goes round once for each person at the table, and the inside loop puts down a fork, a spoon and a cup. How many things do you put out for three people? Check with a grown-up: it is nine. Then try four people.
Do the Mission: set the table together like a nested loop. The outside loop goes round once for each person, and the inside loop puts down a fork, a spoon and a cup. For three people it is nine things, and for four people twelve.
