Although we could not completely finish our last math unit, students got a look into Data Analysis, gathering information and presenting in visual forms such as pictographs and bar graphs. In class, students performed exercises teaching them how to read information from pictographs before constructing their own.

For our math unit in Geometry, we covered many concepts from understanding the basic properties of 3D shapes to lines of symmetry. Compared to our other math classes, this unit was full of lessons that involved an element of visual understanding. Students did a great job drawing and cutting out different shapes, making symmetrical patterns, and constructing 3D shapes out of clay. In math, Grade 4s have been working on the Measurement unit. This means learning how to read time on digital and analog clocks, or in 24 hour and AM and PM time. Additionally, we have been looking at area, using grids to measure area in square units, cm², and m². As usual, we explored the concept of area through games but also creating 1 m² out of paper. It really helped to visualize just how big that area is!
Students have spent just over the last month working on their understanding of fractions and decimals. We worked our way up from interpreting simple drawings of fractions to working with decimals to the hundredths. Below is a look at some of the games students played and teacher tasks given to them.
Students have been continuing to learn about numbers up to the thousands. In class, we have played games to help practice adding and subtracting these large numbers. Some games are played online while others involve playing against a partner. For example, students play a game where they pick cards and make 3-4 digit numbers from them. They then make numbers, trying to see who can get the highest sum, or other variations such as a difference of 300. The unit is almost over and students have been working hard!
In Math, we are a couple weeks into our new unit on Whole Numbers. Students have been working with numbers up to 10 000. We have been looking at place value (thousands, hundreds, tens, and ones) and comparing different numbers (greater or less than). We also recently used Google Drawings to organize numbers into different types of diagrams (Venn Diagrams and Carroll Diagrams) based on their attributes, such as being an odd or even number, or having a certain number of digits. It can get a bit confusing at times, but students handled the task well!
In Grade 4 this year, math lessons involve students rotating through different math stations. After receiving a teacher lesson, students go through 4 stations in total. The stations are described below: Math Facts - Students practice worksheets that review basic math skills. At Your Desk - Students complete their assigned homework, including math workbook, textbook, and online assignments. Teacher's Choice - Students work with the teacher to complete an activity that reviews the new concepts learned. Hands On - In partners or small groups, students work with math manipulatives to complete an activity or game.
With 4 stations, our classes are quite busy but the Grade 4s have done well to manage everything! As we finished learning about area and measurement, students were given the task to make a m² out of coloured paper. From their construction, students were able to see the vast difference between a cm² and a m². We then discussed situations where we would measure using meters as opposed to centimeters, for example measuring the area of the chalkboard or the classroom floor. Below are some pictures of the construction process.
In Math, we have been learning how to read both analog and digital clocks. Students practiced reading time by playing a matching card game, matching the times from analog clock cards to digital clock cards. Whoever got the most points out of 9 won!
In Math, students have been learning how to multiply 2 and 3-digit numbers by 1-digit numbers. To help practice, students played a game where they rolled a dice numbers 0-9. Using these numbers, they filled in a blank multiplication template, trying to get the highest product possible. Students learned that rolling a 0 was dreaded, and that rolling a 9 would bring the best result. The games definitely got heated!
