4 · 14 equals 10 plus 4. The ones part is 4.
5 · 3 plus 2 equals 5. Count on 2 from 3.
True · Ava is right. Both equal 5. Swapping the order does not change the total.
4 · 14 is 10 and 4 more. Ten and some more makes the teen number.
3 · There are 3 circles in the list.
10 · Each step adds 2. 8 plus 2 is 10.
10 + 4 = 14 · 14 splits into 10 and 4.
15 · Each number is 3 more than the last. So 12 plus 3 is 15.
No, both equal 8 · Order never changes the total when adding. Emma is wrong: both equal 8.
False · Leo is wrong. The pattern adds 5 each time, so the next is 20.
