We have started subtraction! Although we are starting it now, we will continue to do addition and subtraction all year to further consolidate those skills necessary for quicker computation and deeper understanding. If your child is struggling, don't worry as it is early days. I will be starting 'borrowing' or 'regrouping' with subtraction with the Grade Two students in particular. I will share more information about that as we get further into the unit. For now here are some great strategies to help your child with this skill:
1. Counting back - start with the bigger number and count back (11 - 3 + think 11, 10, 9, 8)
2. Zero Facts - when you take away all, 0 is left. 7-7 = ___think : take away all, 0 is left
3. Doubles - if you subtract half a number, think of the doubles pictures 14 - 7 = __ picture days in 2 weeks
4. Use a Ten-Frame - when subtracting 9 or 10, think of your 10 frame 10 - 4 = ____fill it up, take away
4 and 6 are left
5. Counting Up - when the numbers are close neighbours, count up...11 - 9 = think 9, 10, 11---that`s 2
6. Think Addition - think of the related addition fact...if it is 13 - 8 = ___ think 8 = (what) = 13 8+5=13,
so 13-8=5
Science: Building Mountain Climbers
The Grade One students are learning about Energy! Recently, the students in both grades built their `Mountain Climbers`to demonstrate the use of `muscle power`to move their mountain climbers. If you know me...you will know that I occasionally suffer from `malapropism`. So, I kept admiring the students `muscle men` or hairy mountain men`, only to hear a chorus of MS FINK, IT IS CALLED A MOUNTAIN CLIMBER!!!...Oh well, here is a video...
