We have been looking at adding the tens first then the ones using place value blocks. We have also been using uni-link cubes and Popsicle sticks so they become familiar with seeing tens and ones in various forms.
In this video, I am asking them to partition (break up) the numbers, which will help them as they move towards stage 5 and eventually stage 6 strategies. In this video I gave them more than ten ones (units) so that they would need to identify that there were another ten within those ones that needed to be added to the existing tens. They became a little confused at the end but as you can see they did work it out. The next step is to begin to withdraw the materials (blocks) and add in numbers so they can make the connection between the concrete materials and abstract numbers. We will try this then I will post the next video just keep checking back : )
awesome working out
