The next number we tackled was tricky number 13.
I am saying tricky because children often forget this number whilst counting. Some children might have come home saying Ms. Geraldine did a lot of mistakes with number 13 today because she was saying three – teen and then correcting it and saying thirteen.
I do this on purpose to make them aware of the pattern in a number line 12, 13, 14, 15 just like I had done for twelve. (See previous blog).
A video clip which helps the children see the pattern in numbers is the following:
Numbers in the Teens (They Start with a 1) (song for kids about teen numbers)
After seeing where number 13 stands in respect to the other numbers on a given number line we practiced counting using various objects such as craft sticks, blocks, bottle caps and more. They became aware that 13 is made up of a 10 and a 3 just like the numicon shapes above.
They also counted 13 tiny spots and stick them onto a lizard print in their Malta scrapbooks after colouring it in. They also used the rainbow technique to form number 13.
We will be working with number 13 next week as well.
