In math this week, students continued to study and master numeration concepts in class. We have been representing numbers to 10 000 using numerals, number words and sketches. We talked about relating thousands to hundreds and to tens by discussing others ways to describe each number (example: 70 hundreds is 7 000, 99 tens is 990). Students also worked on representing numbers in expanded form or notation (ex. 9 235 = 9 000 + 200 + 30 + 5), and practiced writing number words by writing “cheques” in varying amounts (ex. 5 432 = five thousand four hundred thirty-two). 4A & 4C also learned and played two games in class, "Target Addition" and “Place Value Yahtzee." Place Value Yahtzee is a great game to play to practice place value, addition and numeration vocabulary. The website/score sheets are attached below to play at home.
Place Value Yahtzee Game
In science, students learned about plant and animal waste and how they are recycled in nature (the Nutrient Cycle). We went outside to look for and sketch examples of natural waste around the school and in the community garden. Some examples of natural waste we found were sticks, leaves, bark, pine cones, feathers, spider webs and rabbit droppings to name a few. We also saw some decomposers as well like ants and beetles. Unfortunately we didn't see any mushrooms this year as it's been too dry. We discussed the important role of decomposers in breaking down waste and watched a short video about bacteria. We also started an experiment on Wednesday called “The Banana Peel Experiment!” to see what would happen to a banana peel over time when placed in a plastic bag. Students were asked to predict what would happen to the peel in one week and in one month. We will check in with it next week! Yesterday, we went outside again to search for man-made waste and made note of what it was and what it was made of. Unfortunately, we found lots of examples like: plastic bags, a water bottle, a juice box, KD bowls, a plastic fork, and paper products to name a few. We were disappointed to find so much waste around the school. Students watched a short video that introduced the 3 C's--conserving, cleaning up and chiming in. We only have one planet so we need to take care of it!!
Have a wonderful weekend!
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!
In math this week we started off by each student writing their “Mathography” to let me know about themselves as a mathematical learner and their past experiences in the classroom. We also started working on numeration concepts in class. We watched a video called “Number Sense” which was a great overall review for students, and then played the game “Place Value Pick." We also worked on modeling numbers. We made three-digit numbers using the base-ten blocks and then modeled the same number with more blocks. Students learned and played two games called "Stuck in the Mud" and "Let It Roll." Both are good games to practice those basic facts in addition (I've attached the rules below if you want to play at home!).
In science we started our first topic “Waste and our World.” Students listened to the book Just a Dream by Chris Van Allsburg which conveyed the message of how important it is to take care of our Earth. In this story, Walter is careless with his trash and scoffs at planting trees to help the environment. Then he has a dream that takes him to the future where he discovers an Earth that's uninhabitable due to air and water pollution. When he wakes up from his dream, he realizes the importance of taking care of our planet and home. Students were able to look at and read other related books stored in the classroom on our new topic. We also discussed the 3R’s (reduce, reuse, recycle) and brainstormed ways to reduce & reuse in our daily lives and with everyday objects.
Have a great weekend!
We had a successful first week back and I'm enjoying getting to know all my grade four students! Along with setting expectations, getting to know each other and becoming familiar with their new school, grade 4's participated in some fun activities this week such as the BBQ lunch, homeroom relay challenges, assemblies, and the Stampede pancake breakfast. Students learned and played some new math games as part of our mini-schedule rotation on Wednesday and Thursday, and were able to meet all their new teachers. Students received their agenda at the end of the week and a copy of their schedule is in their front pocket (I've attached 4A's below--Monday will be a day 1). Parents are asked to read over and initial the agenda message everyday. A reminder that it is "Think Pink Week" starting Monday with daily activities to raise money for "Run for the Cure" (the activities can be found on the team home page). Have a great weekend and I look forward to starting our regular schedule next week!
I'm looking forward to meeting all my new grade four students next week. We have lots of fun activities planned and I look forward to a positive & productive school year. Have a wonderful long weekend and we'll see you next Tuesday at 8:30 in the small gym!
