53. How can we make 5,126 into 5,246?
5,246 > 5,126, so we must need to add on to it
What is the difference between the two numbers?
• Both have 5 thousands- we don’t need to add on any more
• 5,126 has 1 hundred. 5,246 has 2 hundreds- we need to add on 1 hundred to make
2 hundreds
• 5, 126 has 2 tens. 5,246 has 4 tens- we need to add on 2 tens to make 4 tens.
• Both have 6 ones
Altogether, we need to add on 1 hundred and 2 tens= 120
So, 5,126 + 120 = 5,246
