Directions: I have 2 ten-frames that have counters on them. One is full and one is not. What is the largest number I could make? What is the smallest number I could make?

### Hint

Start by filling in one of your ten frames with counters.

What does it mean to be the smallest number if one of the ten frames is full and one is not?

### Answer

Largest: 19

Smallest: 11

Smallest: 11

Source: Brian Kelley

If 1 ten frame is full and 1 ten frame is not: we could have 11,12,13,14,15,16,17,18 or 19, but not 20.

Jade says 10 is the largest and 11 is the smallest

We can have 19 and 11

Largest number is 19

Smallest is 11

19 is the biggest

11 is the smallest

Smallest should be 10. Because there is no indication that any markers are on the second 10-frame. This same question is on here somewhere but with one 10-frame using its rows. This does cause a contradiction.

The smallest would be 11 since the directions state that both ten-frames have counters on them.

This is very hard

I need help. This is a little unclear to my kindergarteners

I’m grandma. Please tell me what a counter and a frame are in math? Sorry to be so dumb. Can’t even do kindergarten math.
