Subtraction of 2-Digit Numbers 33

Interesting. Is there any Yes, let me introduce the
other way to find out? number line that will display
as many lines as the total
number of balls including
zero in ascending order.

Now to solve the problem, start at
28 and move 12 spaces to the left.

1 1 1 1 1 1 1 1 1 1 1 1

0 1 2 3 4 5 6 7 8 9 10 11 11 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

So, the answer We can directly jump back
of 28 – 12 is 16. 10 steps and then go 2 steps
back to reach the answer.

Mumma!
You are great at all.

1 1 10

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

Prepare some worksheets for the students covering a range of 2-digit numerical subtracting
applications. Give them to the students and instruct them to begin working on the assignment
as soon as the stopwatch starts. Set the timer for five minutes. The one who complete the
