Place Value

We have started a new unit in Math Workshop on place value. Place value is part of number sense, and helps us understand counting, writing, and grouping numbers. It will provide a foundation for students to work with bogger numbers as we learn double digit addition and subtraction.

For this unit we will be using a Marilyn Burns Replacement unit. It is very hands on, and has a lot of writing in it as well. So far we have talked about the 0-99 chart and patterns the children have noticed. They have practiced different grouping strategies, with an emphasis on grouping by tens. Yesterday we learned how to play two new menu math games: Cover a Flat and $ Signs. The first is played much like Race for a Dollar and involves rolling a die and exchanging groups of 10 cubes for a stick worth the same amount. Whoever can get 10 sticks to trade in for a flat wins the game. $ Signs has the children using the clock to time 1 minute increments, and then counting the $ signs they draw in that amount of time. Counting is done two different ways and is encouraged to be grouped in tens once again. We will be learning other games in the weeks to come to practice these skills.
