Decimal Place Value - Popsicle Decimals - Google Class OnAir episode

Below is a video and reflection of a place value lesson I recently did with my children. As mentioned in an earlier post I was challenged to use materials as a way of building the children's decimal place value knowledge. This was my first attempt. To see examples of the children's finished work please go to my Class OnAir site.

I found this lesson a bit of a struggle. Some of the children were reluctant to engage, maybe because they thought they were beyond this however evidence from their classwork and GLOSS test indicates otherwise. This lesson highlighted to me how important materials are for teaching decimal place value. With using materials the children quickly latched onto the idea that 1 popsicle stick represented 1/10 so 3 popsicle sticks represented 3/10 and so on. It also made it easier for them to add decimals together. The next steps involve removing the scaffolds and getting the children to work with tenths without the popsicle sticks
