This week we continued to explore large numbers up to 1 million. The focus was to have the kids understand that as you move through the place value chart it gets ten times great. For example: 100 is ten times greater then 10, but 10 000 is one thousand times greater than 10.
The problem of the week was a way for the kids to work through this concept at home and even challenge themselves a bit further. Today in class I handed back their Problem of the Week and we talked about how 100 ፥ 4 = 25, but 100 ፥ 25 = 4 to try and see the relationship between these numbers. We then tried to expand our knowledge to see that 1 000 ፥ 25 = 40 (ten times greater) and 10 000 ፥ 25 = 400 all the way to 1 000 000 ፥ 25 = 40 000. These types of problems will not be on the first quiz.
Next week there will be no problem of the week as kids are expected to practice and review for the quiz each night at home. Attached is a document that is a quiz review and explains what they are expected to be able to do. The students will also be given practice questions next week and will be offered the chance to pick a station they would like to work at if there is a particular area that is a need. We will also continue moving forward to look at rounding and estimation, then addition and subtraction of large numbers.
Our first math quiz will be on Friday, October 6th. I have attached a review document and some practice questions for the students to complete at home.
