Making Numbers Unifix Cubes - Top Teacher - Free Printable

Let’s solve this step by step.

We are making number sentences that add up to 9.
That means we need two numbers that, when added together, equal 9.

We’ll start with 0 and go up:

- 0 + 9 = 9
- 1 + 8 = 9
- 2 + 7 = 9
- 3 + 6 = 9
- 4 + 5 = 9
- 5 + 4 = 9
- 6 + 3 = 9
- 7 + 2 = 9
- 8 + 1 = 9
- 9 + 0 = 9

But looking at the worksheet, there are only 9 rows (not 10), so maybe they don’t want both 4+5 and 5+4? Or perhaps they just want unique pairs without repeating in reverse? Let’s check the image again — actually, the right side has 9 blank lines for equations. So likely, they expect all combinations from 0+9 up to 9+0 — but that’s 10. Wait — let me count the boxes on the right: yes, 9 rows of cubes, each followed by an equation line.

Hmm — maybe they skip one? Or perhaps they start from 1+8? Let’s think like a teacher would for young students.

Often, for “making 9”, teachers accept:

1 + 8
2 + 7
3 + 6
4 + 5
5 + 4
6 + 3
7 + 2
8 + 1
9 + 0

That’s 9 equations — perfect! They probably don’t include 0+9 because it’s less common to start with zero in early grades, or maybe they do — but since there are exactly 9 spaces, and 9+0 is included above, that fits.

Wait — let’s list them in order as you’d build towers:

If you use colored cubes, say red and blue, you might do:

- 1 red + 8 blue = 9
- 2 red + 7 blue = 9
- 3 red + 6 blue = 9
- 4 red + 5 blue = 9
- 5 red + 4 blue = 9
- 6 red + 3 blue = 9
- 7 red + 2 blue = 9
- 8 red + 1 blue = 9
- 9 red + 0 blue = 9

Yes — that’s 9 different ways. Perfect match for the 9 rows.

So here are the answers for the right-hand page (“Making Numbers” for 9):

Row 1: 1 + 8 = 9
Row 2: 2 + 7 = 9
Row 3: 3 + 6 = 9
Row 4: 4 + 5 = 9
Row 5: 5 + 4 = 9
Row 6: 6 + 3 = 9
Row 7: 7 + 2 = 9
Row 8: 8 + 1 = 9
Row 9: 9 + 0 = 9

(Note: Some classrooms may prefer starting with 0+9, but since there are only 9 slots and 9+0 is more natural as a “full tower”, this ordering works.)

Now, for the left page — it says “Making Numbers” for 5. There are 6 rows of 5-box towers.

So we need pairs that add to 5:

Possible pairs:

0 + 5
1 + 4
2 + 3
3 + 2
4 + 1
5 + 0

That’s 6 pairs — matches the 6 rows.

So for the left page:

Row 1: 0 + 5 = 5
Row 2: 1 + 4 = 5
Row 3: 2 + 3 = 5
Row 4: 3 + 2 = 5
Row 5: 4 + 1 = 5
Row 6: 5 + 0 = 5

Again, some teachers might skip 0, but since there are 6 rows and 6 possible pairs including zeros, this fits.

Final Answer:

Left Page (Making 5):
0 + 5 = 5
1 + 4 = 5
2 + 3 = 5
3 + 2 = 5
4 + 1 = 5
5 + 0 = 5

Right Page (Making 9):
1 + 8 = 9
2 + 7 = 9
3 + 6 = 9
4 + 5 = 9
5 + 4 = 9
6 + 3 = 9
7 + 2 = 9
8 + 1 = 9
9 + 0 = 9
