Base ten blocks are a new manipulative that has been introduced in Grade One. Children in Kindergarten are very familiar with five and ten frames but the base ten blocks are brand new. During September and October children have been exploring the base ten blocks during Guided Exploration by building with them, sorting them and by counting the sections. During the month of November we have been using the Base Ten Blocks to represent the date on the calendar. Children in grade one need to learn to represent numbers to 50 using a variety of math tools (10 Frames, Base Ten Blocks, Number Lines, Coins).
Counting on is an essential skill when using base ten blocks and practising this concept is helpful. For instance you could put one of the rods (base ten block worth 10) down and then 7 of the ones and your child would say 10 then count on to 17 by counting the ones. Counting on is essentially saying the biggest number and then counting on the rest to see how many you have altogether. Children need to develop this strategy on their own and, with lots of practice counting on in different situations, they will.

At school have been using a 10 Frame as a tool for representing numbers. Please take some time to watch the first video as it explains the concept of a 10 Frame for parents. The last 2 videos are games to play. As your child gets better at understanding numbers represented on the 10 Frame he or she will be able to get more of the answers correct in the game videos without having to count each section of the 10 Frame.
