Inspired by the Chinese abacus (which they called suànpán) I adapted the Montessori Teens Board to create our own little counting set. My objective is to teach the teens.
Each Counting Set has two 10's strands (black), two 5's strands (red), and 10 ones (gold), plus a counting mat, number cards and a drawstring bag for the beads. I used the colors that brought the mood of China to this activity.
Here's what you will need: 1 piece of glitter foam (I purchased the largest size and cut it into fourths), pony beads in black, red and gold, gold pipecleaners, and a small drawstring bag.
Preparation of Materials: I set up the materials to make the construction as simple as possible. I precut the pipecleaners (I cut the 10 strand 5 inches long and the 5 strand 3 inches long. This gave room for the children to make the end loops. If you make the set, it will not need to be this long.) I laid out each child's materials so that it would be clear when I gave them the instructions.
Making the strands: I told the children that the “black beads on tall, red on the small” in regards to the pipecleaners. I repeated this several times. I also demonstrated how to make a loop and twist on the end of the pipecleaner. I walked the children through the first strand. I set them loose to make the 2 black strands and 2 red strands, put them in their bags and count 10 gold beads into the bag.
I talked a little about how we can call the 10 strand just “ten” and the 5 strand just “five” and the single gold bead “one.” Tomorrow we will begin to put out the number cards and explore how tens, fives and ones make the numbers 1-20. We will concentrate on 11-20. Be clear! This is not the full Montessori method! I am adapting the idea for my situation.
