We are learning how to solve subtraction problems
The soldiers shoelaces were eaten by rats. The shoelaces were 33cm and the rats ate 5cm. how long are the shoelaces now?
We solved it by splitting the 5 into 3 and 2.
We split numbers to solve subtraction problems efficiently.

|Sienna checking her shoelaces. Will they be long enough now?|

|Jack and Ella measuring their shoelace |
after working out 23cm-4cm using their counting back.
|Erin and Whetu using their counting |
back on a number line to solve the problem 31cm-4cm
|We worked together to solve some word problems. |
We made number lines and used our backwards counting in ones to figure out how many cm's of our shoelaces were left after being gnawed by gigantic rats in the trenches.
