We got to visit the expert mathematicians in 4C this week who helped us explore a variety of math concepts as we rotated through their presentations and activities. The grade four students had prepared lessons, games, and online suggestions for our class to work on curricular math concepts, and we had a blast learning about math from them!
We’ve been working on data analysis in Math recently, and the class has enjoyed collecting and analysing a variety of information. In this unit, your child will be learning about graphs, and about asking questions to gather information! The Learning Goals for this unit are to:
You can help your child reach these goals through the following activities:
In Math, we are beginning a new focus on geometry. In this unit, we will be learning about 3D objects such as cubes, spheres, cylinders, cones, and pyramids, as well as 2D shapes such as triangles, squares, circles, and rectangles.
The learning goals for this unit are to:
You can help your child achieve these goals with the following activities at home:
You can also play the video and games below for extra practice at home!
We made good use of our two-digit addition and subtraction skills this week as the students set up their own classroom stores and went shopping with pretend Millgrove Gift Certificates. There was lots of adding sums, subtracting to figure out change, and thinking about how we use math in our everyday lives. We also performed some price comparisons between items from a toy store flyer to see the difference in price using subtraction.
Recently we've been working with dot collections from Gerri Lorway to look for smaller groups of dots within a set of them. The students have loved using these different images to estimate the amount of dots after just seeing them for a flash, and then analyzing the sets of dots to decompose them into different groups. This helps us to use the commutative property and associative property (see above), and as Gerri Lorway says, "The ability to flexibly name numbers is foundational to building long term recall of facts."
The students to 2B have been demonstrating growing skills with two-digit addition and subtraction, so today they were given a mission to make a pretend selection of toys for themselves using online children's stores with a budget of $100. All the students stayed within the budget (with a few approvals to go over budget if their three-digit math was accurate), but their selections and adding strategies were varied and impressive. We look forward to planing more shopping trips with our math skills!
We've been practicing our estimating skills in 2B this week, and the students have become more comfortable with having an informed estimate that doesn't exactly match their subsequent count. In grade two, students use referents to help inform their estimates, and the class is getting impressively accurate with their estimates of amounts up to 100!
We're almost done our focus on measurement in Math, and the students have really enjoyed measuring mass using a variety of units. They've become pros at estimating, measuring, and comparing different masses, and selecting the appropriate unit to use when measuring mass. Check out some of the games we've been playing during this unit below!
