I hope you liked the guest post Denise did yesterday!  I never knew you could do so much with Spelling City!  If you missed it, check it out here!

A couple weeks ago, one of my kindergarten teachers and I were talking about their math centers.  Last year, after I saw a great blog post from Adventures in Teaching about BUILD math centers, the teachers tried them out.  While they’ve loved them, there’s been a few kinks we’ve been trying to work out.  We even talked about doing away with it and trying something else but they decided to stick with it.  In the process, we talked about needing more activities to go along with the hundreds chart.  There are just so many ways the hundreds chart can be used to help build number sense.  I was shocked to find so little about the hundreds chart in the common core standards.  Don’t get me wrong, it’s there, but I expected so much more.  I think the kids need to use it to add and subtract.  They need to see how it relates to place value.  Have you seen the same thing?  I’m thinking it’s just not explicitly clear and we will see more with it as states make their own curriculum maps and we see the standards unpacked more.

A while back, I created these missing number puzzles using the hundreds chart.  There are 20 different puzzles.  They get more difficult (with additional missing numbers) as the pages go on.  You can differentiate them in your class for your students or slowly introduce them as students get more comfortable with them.

But, we needed some additional ways to practice.  So I brainstormed, and created some rocking activities ๐

I worked on creating some hundreds charts activities that can be used as a center.  I created them in different levels.  This way, you can introduce them at different times throughout the year.  Or, you can use them to differentiate for your students.

There are three different levels for the number lines.  The pages are 0-20, 0-50, or 0-120.  The title changes color to help you identify when the level has changed.  There are two cards on each page and each card has two number lines.

There are also 3 different levels of the number puzzles.  The first level is 0-20 (since you can’t do the grid to 20).  The second level is 0-120.  The third level is a 5 grid puzzle instead of a 9 grid puzzle which requires much more in depth thinking.  There are also far fewer numbers filled in.

The final activity is to-do cards.  Students draw a card and use the number chart to solve the problem.  I provided recording sheets with an answer key so students use the number next to the star to record their answer and can self-check their work.  Again, this activity also has three levels.  The first set is again only numbers 0-20.  The second is numbers to 120 using addition.  The final set uses both addition and subtraction.

There are 8 pages for free in my TpT store.  You can get them free here.
The full unit is 58 pages (my biggest yet!).  You can get it from TpT store here.
