One really important concept to remember with larger numbers is that we can represent them using materials like base 10 blocks. I can represent 245 using different combinations of blocks. See the examples below.
We are also representing money amounts using coins and bills (to $10 in Gr 3 and $100 in Gr 4). Note that in French, the dollar sign goes after the money amount, and the decimal point is represented with a comma, rather than a period. [ 4,25$]
We want to be able to count up from 4,35$ to 5,00$ for example, to give change. A terrific way to practice this is to play store at home. I've also added practice activities to Prodigy and Study Ladder.
Finally, we are beginning to look at rounding. This week, I just want students to be able to find the nearest 10 or 100 to any number. We will be using a human number line in the classroom, to make sense of this important number concept.
If you have any questions, please don't hesitate to contact me in the agenda.
