Compose/Decompose Numbers and Place Value

Hi!! We are back!!Wow! We have been missing for a while!!! Crazy times are just beginning!! We can't believe how fast the year is flying!!

Assessment time again for us!! How do you assess Composing/Decomposing Numbers and Understanding Place Value??? Our Kiddos have been playing an awesome game from Envision Math Centers! They are having a blast. You could play it even if you don't have Envision Math.

What do you need??
Each group needs
A 100 chart
2 sets of Number tiles/cards 1-9 in a baggy
Base 10 blocks

How do you play??
Students take turns pulling out 2 number tiles (students can put either tile first unless it is a 0) For example, if a child pulls a "4" and a "1" out of the bag then he/she can work on the number 41 or 14.
Student places the numbers above the 100 chart
Student points to the number on the number chart
Student builds (compose/decompose) that number with the base 10 blocks (using units of 10s and 1s)
Students play until all tiles are gone from the bag.

While we are continuously observing students playing this game and working on place value in other ways, we still love having some documentation as proof that the kiddos really did or did not meet this standard.

So we made these. What do you think?? Grab them if you want.
