Five is a good number to know. You have five fingers on one hand.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
Big numbers hide a five
Seven is a full five and two more.
7 beads moved across in total.
How many
5 and 2 make 7.
Beads
So you do not start at one. You say five, then six, seven.
Why five and not some other number
You can see five at a glance because it is a hand. Anchoring bigger numbers to something you never have to count is what makes them quick.
Check yourself
Cover the five. Can you still say how many are left over? If you can, you are using the anchor rather than counting from one.
Step 2: Try It Yourself
Slide the beads and watch the five.
6 beads moved across in total.
How many
5 and 1 make 6.
