    Hi, Jack here!
    It was hard for me to do the addition and subtraction post test.
    I’m feeling confident in my results because I have been improving on my Jump strategy and my split strategy.
    I like doing Addition and Subtraction tests because I feel confident on the easy learning areas.I think I am learning lots.
    Bye from Jack

    Dear fellow bloggers,

    I absolutely love the ‘Jump Strategy’ and the ‘Split Strategy’ because these are easy ways of working out addition and subtraction. The ‘Jump Strategy’ is my favourite because I love how there are so many ways of using the the ‘Jump Strategy’ in equations! I like the ‘Split Strategy’ because the way it’s done! So, what is your favourite one?
    So, see ya later!

    From Lachlan
