Christine Rowe Quinn, the math coach for our family of schools, worked with Areas 3 and 6, once a week for the whole month of April. With her help we learned all about the various ways we can make numbers 1 through 10.
We made dot plates to represent numbers to 10 in the configuration shown on dice. We also traced our hands and then cut them out to show how to make numbers to 10 using our fingers.
We also used 10 frames which look like 2 rows with 5 boxes each all joined together. Each frame holds only one counter and the frames are filled from left to right starting with the top row of 5 boxes. We used the 10 frames like flash cards to see if our mathematicians could recognize at a glance what number was represented on the 10 frame.
A trick for reading the 10 frame quickly is to use the upper row as a base of 5. So if the top row is filled then that represents the number 5 and the quickest way to recognize the number 4 is to see that one box on the top row doesn't have a counter or 1 less than 5.
Mathematicians noticed that the number 7 is represented by 5 counters on the top row and 2 more on the bottom row or they may have recognized 7 as being represented by the last 3 boxes in a 10 frame not having any counters or 3 less than 10.
Although many JK mathematicians recognize number symbols to 10 (6 and 9 being the main confusions), they often refer to the number board to see how to form these numbers and as an extra challenge, we also wrote out the words for numbers 1 to 10.
At the end of our unit mathematicians were asked to make a number train of 10 linking cubes using 2 different colours. We had a friend check our work and then we represented our number train using the same colours by drawing our number train on graph paper so that it matched the linking cubes we used and writing the corresponding numerals that together made 10.
After looking at everyone’s work we noticed that 10 and 0, 9 and 1, 8 and 2, 7 and 3, 6 and 4 and finally 5 and 5 all make the number 10!
