Whether you are talking about simple addition, finding the total, sum or adding one or ten more, the addition section covers partitioning, through to the standard compact method. Plenty to keep them busy.
Good simple activity for R or possibly early Y1. Could be used at the end of a lesson on the interactive white board by the whole class as a quick quiz.

No promotion jokes please. This is a great resource to develop quick fire responses to simple add and subtract sums. We didn't find any sums with double digits in. There are 4 levels - best to have a play - start with level 1 as responses need to be seriously fast - just like your promotional journey to the top.

We love this game - use the help first though. We needed to. It encourages children to think about the number they need to get them to the next ten. So if you start from 34 - type in 6. This gets you to the next ten. Great.

This activity is visually simple and requires little explanation. Could well be used effectively with a small group or as part of a mental starter. It starts with adding numbers on dice. So no more than a total of 6. It then moves on to using written numbers.
Requires the ShockWave plug-in from Adobe to work.
