We've been working on estimating in Math this week, including talking about how our estimates need to be informed and logical but not perfect, using referents (a smaller group of objects) to make an accurate estimate, and comparing our estimates to our counts. We also used skip counting strategies to more accurately and efficiently large groups of items. There are some great number sense and estimating gurus in our class!
We've been busy with numbers up to 100 recently in Math, whether we were skip counting with money (a big highlight), investigating even and odd numbers, counting toothpicks like Raymond from Rain Man, and using ordinal numbers to describe objects (such as first, second, 3rd, 4th). The students were expert money counters, and felt quite prepared to spend their pretend money! If you'd like more practice at home with numbers to 100, the linked games below are focused on some of our learner outcomes for this unit.
In Math, we are beginning a new focus on numbers up to 100 and solving word problems. This unit will focus on deepening your child’s understanding of number relationships, counting, and place value. Below you can find a game and video we've been playing to get this unit off to a fun start!
The learning goals for this unit are to:

We are wrapping up our focus on increasing patterns in math this week. Increasing patterns are a brand new concept in grade two, and can often prove to be tricky, but the students in 2B have worked hard to describe, reproduce, extend, and create increasing patterns over the past couple of weeks. You can practice increasing patterns by taking the link to the game below!
Continuing with our work on repeating patterns, this week our class learned about the process of designing fabric, and used our knowledge of repeating patterns to design our very own fabrics and identifying their elements, rules, and cores. The class made some convincing advertisements about why potential customers should purchase their fabric, and did a great job of describing their patterns using mathematical terms. The only downside of some of these fabrics was the seven figure price tag that many of them had!
In our continuing work on repeating patterns, we enjoyed touring the school this week in search of repeating patterns around Millgrove. We found that repeating patterns are truly all over the place, and the students composed collages of some of their favourites. Even Mr. Cherry had an AB pattern when we were searching close to his classroom! It’s neat to see that the concepts we learn about in Math time are visible all around us in real life.
We have been patterning up a storm here in 2B! Patterning is one of our first units in math, along with skip counting and word problems. This past week we worked hard on repeating patterns, and will soon learn about increasing patterns.

We’ve really been enjoying playing Breakout Edu games this past week to review our learning in grade two this year. The Breakout box is a student-friendly version of breakout or escape rooms where people have to solve puzzles to escape the room. In our Breakout games, the students had to use their knowledge from math, science, and social studies to solve a variety of clues that unlocked the locks on the Breakout boxes (which contained small prizes). So far the students have beat the timer on all our Breakout Edu games, which is no doubt a testament to both their knowledge of not only these subject areas, but also their problem-solving, communication, collaboration, and critical thinking!
Using our knowledge of 3D objects from our learning about geometry in math in grade two, each student got their own Tinkercad account this month where they could design with a variety of 3D objects with all sorts of vertices, edges, and faces. After working through some tutorials on Tinkercad on how to manipulate and design objects, students used the "Key Ring, Letters!" tutorial on the website to create a custom-designed Father's Day keychains for their dads and grandpas.
Each keychain turned out very special, and they ranged from Star Wars designs to Stanley Cup models to affectionate words of endearment. The students were very proud of the designs that they worked on so independently, and the highlight of the whole project was the printing process when they got to see their keychains gradually take shape on the printer bed. It was meaningful for students to make the connection between their math learning and how that learning is useful in the world of design!
In our unit on data analysis, students have been coming up with their own research questions to collect data on, and they’ve become experts and surveying their peers about a variety of topics. We've practiced graphing our data, comparing data, and identifying important results. You can see some of the data collected below!
