Counting Collections
You are going to LOVE this math lesson. I LOVE this math lesson. My principal LOVES this math lesson. My students LOVE this math lesson,....
So you have recently gotten through base 10 lessons in your math te. Students seemed to whiz through it,...but you get the feeling they STILL don't fully grasp place value to 100. And this might be because the lessons from the program "led students" too much. The activities maybe did not allow for enough independent thinking. And since this is a new standard (K.CC.1- Count to 100 by ones and by tens), you're not sure how to measure their full understanding of this standard.

A Counting Collections math lesson is reminiscent of the Math Their Way style of teaching (which I love!). Students are issued a tray of a given collection (I precounted to numbers less than 80) with a stack of cups or mini bowls or whatever to hold their manipulatives. As you can see, students are to make groups of 10 in the cups and lay out whatever is "extra" (or in the 1s place).
I have been doing these mini lessons since November. Students know the set up and clean up procedures. I like to select ordinary counting objects like buttons, bag fasteners, corks, rocks,...as well as fun counters like cute erasers, pom poms, shiny gold coins. The combination of counters instills in students that counting can be done with ordinary objects and the fun objects makes counting something to look forward to (they never know which collection they will be issued). The final step is to record their collection. This is the sheet I used back in November when we were counting 1-20.
I think I will try numbers over 100 next time. Most of the students in my class are TK, but they seem to really grasp this concept. I am interested if they can combine their groups of 10 to make 100.
