to 100

Pulling together all of our work with digits over the past curriculum block and a half of math, today we created a 100 chart. We started with blank grid of 100 blocks, and made columns of numerals on the left hand side of each block, skipping the first column. So we wound up with a column of 1s, 2s, 3s, etc up to 9s. I did the first couple of numbers in the column, so the kids could see the example I was setting, then Zoo Boy took over for the next 4 blocks (in this photo he is working on the 3s column).

Then J finished off the last 4 blocks of each column. (He's working on the 4s here.)







Then we went back and filled in the right hand side of each block, with the numerals 0 to 9 in each column. So we created a column of numbers 0 to 9, then a column of 10 to 19, then one of 20 to 29, and so forth. Here J is working on the 40s.



Zoo Boy finishes out the 90s column. I really thought it might take a couple of days to accomplish this, as I figured the boys would get bored with it. But much to my surprise, they actually picked up a head of steam and got more enthusiastic about writing the numbers the further along we got. The entire chart only took us about half an hour to complete, and the kids were never looking for a break.

And here is our completed 100 chart. We hung it up in the hallway for reference, and we'll be revisiting it for an activity with odd and even in a couple of weeks.

This is a nice place to break for a few days. I'm taking the Grace puppy to a training seminar during the day for the next three days, so tune back in next week for more math fun and adventures!
