Lots of word problems today, make sure you're being a good detective and thinking carefully about what you need to do to get to the answer!
I have added some addition and subtraction word problems if you want to keep practising. Choose a few, there are so many so please don't feel like you need to do them all! Remember to say it out loud, build it, draw it and write it as a number sentence in your books, no need to print the questions out.
