Try these riddles: “I am 200 + 30 + 6. What number am I?” (236) “I have 5 hundreds, 7 tens and 9 ones. What number am I?” (579) “I am 400 + 8. What number am I?” (408) “I have 3 tens, 4 hundreds and 1 one. What number am I?” (431) Note: Point out that the last two riddles were a bit tricky since one number didn’t have any tens, and the other one named the number of tens before naming the number of hundreds!
