### Fractions

I just used some cardstock (you can laminate if you 'd like) and made a little puzzle to help with the concept of fractional parts.

### Rounding to nearest Hundred

To help my child learn the concept of rounding to the nearest hundred I used two sentence paper strips to make a number line from 100-900. I cut out 2 x 2" squares of card stock and wrote on some random numbers. We made a little game out of finding which 2 hundreds the given numbers were in between, laying the given number on the number line. Then I marked off the "middles"...150, 250, 350 in red...explaining that if the tens place of the given number is 5 or above then you round up to the next hundred. For example 252 would be rounded up to 300 since the tens place is a 5 or above. I presented this to my daughter by placing the numbers under the correct answer.

### Homemade Montessori Counting Beads

Instead of using the very expensive traditional Montessori gold beads/rods, I decided to make my own beads using natural wooden beads on natural hemp string. I have only gotten as far as beads for 1-10 as seen in the photo. You can find supplies at your local craft store. I tried to tie the knots as close as I could to the beads on each end just so that when you line them up that it is a very clear pattern that the next number is one bead larger, etc. This time I lined them up to look like a Christmas tree for the holiday season.
