In math, we are continuing to work on representing numbers to 10 000. In our math journals we worked on the following: “Explain the meaning of each digit in the number 2 222 in words and pictures.” We discussed how important place value is when talking about multi-digit numbers. Students also solved some number riddles in class and then worked on making their own riddles by creating a set of clues so others could guess. This activity is great for building number vocabulary (place value, odd/even, ranges, sums, etc). Students shared some of their number riddles with the class and we had fun trying to guess their numbers based on their set of clues. Below are some of the number riddles written by 4A and 4C students: I’m thinking of a number between 400 and 600. The tens and ones add up to the first digit (hundreds). The three digits add up to ten. The number is an even number. What number can it be? My number has three digits. It is an even number. It is between 300 and 500. The sum of the digits is 8. The last two digits are the same. What number is it? I’m thinking of a number between 400 and 600. The numbers are consecutive. The sum of the digits is 18. The number is odd. The ones place value is greater than the tens and hundreds place value. What number is it? I’m thinking of a number between 4 000 and 8 000. It is an even number. All the numbers are the same. The sum of the number is 24. What number is it? I’m a four-digit number and I’m all odd. I’m between 5 000 and 7 000 and three of my digits are the same. The tens are greater than the rest and all together I equal 22. What number am I? My number is between 700 and 850. One digit is odd and two digits are even. The last number is the smallest. The sum of my number is 19. What is my number? My number is between 800 and 950 and all the digits are even. The ones is the smallest number. The sum of the digits is 14. What number could it be? I am thinking of a number less than 40. It is odd and the ones digit is bigger than the tens. The sum of the digits is 10. What is my number? My number is between 300 and 500. The hundreds digit is lower than the other numbers. The last number is odd and the other two numbers are even. The sum of the digits is 19. What is my number? My number has 4 digits. It is odd. It is between 1 000 and 1 950. If you add up all the digits it equals 20. What could my number be? In science this week, we continued to discuss the 3 R’s—reduce, reuse and recycle. We talked about the order and if you can’t reduce or reuse your waste first, then at least try to recycle it. We explored the City of Calgary website on the recycling program, and learned what can and cannot go in the blue bin. We watched a video tour of Calgary’s recycling facility (which I’ve attached below) and learned the many mechanized ways they sort the recyclables including using disk screens, magnets, eddy currents and optical sorters. The students found it very interesting! Students demonstrated their learning when they created an artistic visual journal page on the 3 R’s, and wrote some ways they could reduce & reuse at home or school, as well as some things they learned this week about recycling. We also enjoyed the Bill Nye video “Garbage” which introduced another “R” word—rethink (if an item can’t be reused or recycled then rethink buying it). Enjoy the first weekend of Fall! —Ms. Jagger
