The big idea핵심
Some questions have more than one answer. In 63 < □ < 67, the box can be 64, 65 or 66.
To find all the answers, count in order from one end to the other and check each number. Then Lia can say how she knows she has found them all.
In a true or false question, change the tens and ones first. 10 ones make 1 ten.
