Our amaryllis plants have continued to rocket up in their growth! Because we learn about life cycles in grade three, we're continuing to observe our plant "Greeny" as it loses its flowers and will continue to grow its leaves. Our plant "17 Centimetres" has grown exponentially in the past month, and many flowers have blossomed this week.
Our latest measurement of "17 Centimetres" had the plant pegged at a height of 70 cm which means it has grown 53 centimetres since we planted it! You can watch the video below to see a time-lapse of another amaryllis growing.
This month our class is starting a Math unit on multiplication and division! Multiplication and division are basic computational skills that children must eventually master in order to succeed in higher levels of mathematics. The focus of this unit is developing an understanding of the process of multiplication and division in order to develop strategies for multiplying and dividing whole numbers up to 5 x 5. Children will use counters, number lines, and arrays to develop their understanding.
In this unit, the students will:
You can encourage your child to share different strategies used to multiply and divide.
We use multiplication and division in many day-to-day situations. Here are some suggestions for activities you can try at home:
Today we went Christmas shopping in 3B! Given the students' growing skills with three-digit addition and subtraction, they were given a mission to make a selection of toys and other items for themselves with a budget of $1000 using some flyers. All the students stayed within the budget (except for a few who felt confident to add beyond $1000), and their selections and adding strategies were varied and impressive. We look forward to planing more shopping trips with our math skills!
This week, the students were excited to crack out their rulers and begin our unit on the measurement of time, length, perimeter, and mass!
In this unit, the students will:
Here are some activities you can try with your child:
In grade three, we learn about measuring height in centimetres (and metres) and we also learn about the life cycles of plants (and animals). To get started on these learning outcomes, this week we got some plants in our classroom. We will be tracking the growth of these plants over time and observing changes as their life cycles progress. The students especially enjoyed naming their plants, and we are curious to see how the plants grow in the weeks ahead!
In Math this past week, we started a new unit on addition and subtraction. Your child will develop strategies for adding and subtracting whole numbers by using open number lines, addition charts, mental math, estimation, Base Ten Blocks, place-value mats, and pencil and paper.
In this unit, your child will:
Here are some suggestions for activities you can engage in with your child:
On our Participark walk this week, we made use of our math skills as we went on a mathematical scavenger hunt! The students had to make some increasing patterns, count and create some referents using leaves, and practice their estimation skills. We had unexpectedly beautiful weather, and we had a great time in the woods as usual!
We’ve been putting together many of our building number sense skills in 3B this month as we worked on creating amounts with coins, estimating up to 1000, and skip counting by 2s, 3s, 4s, 5s, and 10s. We also enjoyed some graphing this week, and enjoyed reading a book all about animals and numbers. You can try some of the estimation and skip counting games below and take a look at some pictures of what we’ve been up to in Math class!
We've been practicing our estimating skills in 3B this week, and the students put those skills to use on our Participark walk today! 3K joined us on our walk to collet leaves, and we secretly made piles of leaves with different amounts, and then used referent piles to estimate the amount of leaves. The students had some impressively accurate estimates!
The students have become more comfortable with having an informed estimate that doesn't exactly match their subsequent count. In grade three, students use referents to help inform their estimates of amounts up to 1000! You can see photos of some of our math activities from the past week, and click on the game below to practice more estimation.
