Thank you for supporting your child by attending the Gr. 3 Structures Exhibition. It was a great way to end the unit and celebrate how much they have learned and achieved! You can view pictures of the exhibition here.
This week, we will continue looking at the concept of time. Also, we will be reviewing basic addition and subtraction strategies. Students will begin the Mighty Math Challenge by answering as many addition and subtraction facts as they can in 2 minutes. They will have two weeks to practice and learn strategies that will improve their accuracy and speed. On December 2, the students will compete against themselves by trying to improve their original score. You could help your child at home by using the strategies below.
Thinking Strategies for Addition
Students start with a number and count on 1, 2, 3. For example, if the question is 5 + 2, students count 5, 6, 7. Note: This strategy is only useful for adding 1, 2, or 3
The first fact combinations students often learn are doubles.
Students make combinations that equal 10. Then they extend to make combinations that are multiples of 10. Examples: 6 + 4 = 10 extends to 76 + 4 =80. This can then be extended to 10+4=14 or 50+8=58.
Thinking Strategies for Subtraction
Students start with a number and count backwards. If the question is 5 – 2, students count 5, 4, 3. Note: This strategy is only useful for subtracting 1, 2, or 3.
Students start with a number being subtracted and count up to the number from which it is being subtracted. For example, for the question 9 – 7, students can count 8, 9.
Number Grids are helpful for students who struggle to visualize number patterns and counting ‘in their head’.
We will continue to explore Narrative text type and how to use adjectives and adverbs to enhance their writing.
We will continue using SketchUp and drawing 3D structures.
