March 18-21
Thank you to all our parents and families who took the time to join us for Parent Teacher conferences. It is an exciting time of year as we celebrate the growth made already since January report cards and set some goals for moving into the final part of the school year.
We wish you all a relaxing Spring Break with time to spend with family. We look forward to welcoming everyone back on April 2nd.
Here are just a little recap from the week.
Spring (or Winter?) Walk
Although our plan for going to Fish Creek didn’t work out, we still enjoyed a walk outside in the snow. We looked for signs of winter and spring and we transition into a new time of year and season. We look forward to getting outside again soon and hope to reschedule for going to Fish Creek in April.
We found a quiet spot to sit under the trees, to take a moment to be aware of our surroundings and use our 5 senses to connect to our environment. After listening to the sharing of Elder Saa’kokoto through a video, he reminded us of using our spirit, heart, bodies and minds to connect with Mother Nature. We took a moment outside to listen with our hearts, mind, body and spirit and thank Mother Nature for the gifts of our land,
Pathways in the Snow
Learning Intentions:
I can observe and describe direction, pathway and speed
I can observe seasonal changes in local environments
I can discuss how changes in the appearance of environments, plants and animals are related to the seasons
Math
This week, we had a very brief introduction into take away situations. We will pick up and continue this work after Spring Break
What Is a Takeaway Situation?
In a takeaway situation, there are a certain number of items present. These are the whole. Then some items are removed.
These items can be eaten, given away, dropped, or removed in another way.
For example, if there were 10 children in a room and 2 left, this is a takeaway situation.
Using the Subtraction Symbol
When you have a takeaway situation, you can describe it by subtracting what you took away from what you started with. You can use a subtraction symbol to write subtraction.
For example, 8 – 2 can be read as “8 minus 2” and can describe a situation where 2 is taken away from 8. In takeaway situations, you might also read this as “2 less than 8” (which implies taking 2 from 8) or as “8 take away 2.” It might be best to avoid saying “take away” for all subtraction situations, though, since not all are takeaway situations.
The answer is called the difference.
Takeaway Models
You can show takeaway situations using counters on a 10-frame:
It is best to take away the last few counters, not the first counters. Taking away the last few counters will make it easier to see how many counters are left on the 10-frame.
You can show takeaway situations using counters without a 10-frame.
You can show takeaway situations using counters on a number path.
Or
It is best to take away the counters on the greater numbers. Leaving the counters on the lower numbers will make it easier to see how many counters are left.
You can show takeaway situations using a bar model. Show the whole, or the total amount, in the top bar. Show how much you remove in one of the bottom boxes.
Helping Your Child
When takeaway situations with relatively small numbers arise, you could ask your child to tell you what is being subtracted from what.
You might allow your child to figure out what will be left, but that is not the focus in this particular lesson.
For example, if there were 5 plates on the table and you removed 3, you could ask your child what subtraction just happened (in this case 5 – 3).
Notes
Notice that the bar model shown above does not help students figure out what is left. They can represent 11 as the whole and 3 as one of the parts, but a bar model doesn’t show how many are in the other part. However, a bar model does help students represent the whole and the parts they are working with.
