Today we looked at
number lines and
hundred charts as tools for adding and subtracting.
We talked about how when we move right on a number line the quantities become greater and as we move to the left the quantities become lesser.
Some number lines have labelled increments, while open number lines are blank and the learner add the numbers they are working with.
One hundred charts increase and decrease by one as we move right and left like a number line. When we travel up and down the columns we add and subtract ten.
7 , 17, 27, 37, 47....... 62, 52, 42, 32, 22, 12...
Thanks for all the building supplies sent in so far. Keep them coming, we will be able to make some great projects with them.
REMINDER: Remembrance Day assembly on Friday and no school on Monday.
