This week we explored some new strategies to solve addition equations: using a hundreds chart, the jump strategy and the split strategy.  These strategies involve us using lots of different thinking.

The jump strategy uses the thinking of visualising a number line.  We need to break one of the addends into tens and ones to add it on.

The Split Strategy also requires us to think about place value.  It can look like these examples…

Being able to add tens onto a number is a really important skill for both of these strategies to work.  You might like to practise adding tens to a number.  For example: 23 + 10, 56 + 30, 67 + 20.

Some students also explored how using a number chart can be very handy.  In order to use this strategy you have to understand how to move by tens down the chart and then across to the right by the ones:

Here is a number chart you could print at home to practice this strategy with: My120Chart

Can you show mum and dad how you can use these strategies? Which one do you like most? Which one do you think you need more practice with?
