What better way to explore 3D shapes than by constructing our very own 3D medieval village. In the next month, we will classify 3D shapes by their properties and determine the differences between prisms and pyramids. We will construct 3D shapes using a variety of materials including; paper nets and toothpicks and clay.
March to April - Fractions and Decimals

For the next month or so, we will be reviewing our knowledge of fractions. We will be reminded that the top number in a fraction, the numerator, represents the part of whole and that the bottom number, the denominator, represents how many parts there are in the whole. We will also explore equivalent fractions and will be given opportunities to add and subtract fractions with a common denominator.
This year we will be introduced to decimal numbers. We will grow to understand the relationship between fractions and decimal numbers.

February - Measurement

Before and after the TET holidays, we are working on measurement. We will be estimating and measuring distances using standards units of measurement and gaining practice converting units of measurement (example: 10cm = 100mm). We will also look at different strategies for measuring the perimetre and area of quadrilaterals. As well, we will review how to measure time in order to solve word problems that ask us how much time has passed.
Standard Units of Measurement for Distance (in order from smallest to biggest)
millimetres, centimetres, decimetres, metres, kilometres
Measurement Words to Know:
standard unit of measurement, convert, perimetre, area, elapsed time

December to January - Patterning and Algebra
Before and after the Christmas holidays, we'll be looking at patterns in colours, shapes and numbers. Our goal is to determine the pattern rule.
Examples of different patterns are below:
Growing pattern - 1 3 5 7 9 11 (pattern rule: Start at 1 and add 2 each time)
Shrinking Pattern - 71, 66, 61, 56, 51, 46 (pattern rule: Start at 71 and subtract 5 each time)
Repeating Pattern - 12 3 8 12 3 8 12 3 8 (core: 12, 3, 8)
Patterning Words to Know:
growing pattern, shrinking pattern, repeating pattern, extend, create, attribute, number chain, direction

November - 2D Geometry
For the second half of November, we are studying 2D Geometry. We are reviewing basic shapes from Grade 3 and are beginning to classify shapes based on their properties (the number of sides, vertices and by the degree of its angles). We will be constructing various 2D shapes with different lines, sizes and angles. A particular focus will be placed on learning the properties of different quadrilaterals.There are many new words in this unit so please review them often.
Geometry words to know
polygon, vertex, side, right angle, obtuse angle, acute angle, parallel, diagonal, quadrilateral, pentagon, hexagon, octagon, congruent, similar, symmetrical
November - Data Management
In November, our class is learning to collect data through different methods, including conducting our own surveys. We are also learning display our data using a stem and leaf plot, T-tables and bar graphs and analyze and compare our end results. A new concept for us in Grade 4 is finding the mean, mode and median of a set of data.
Data Words to Know - predict, collect, survey, graph, interval, average, mean, mode, median
October - Multiplication Strategies
We learned strategies to help them solve word problems involving multiplication. We learned that multiplication can be considered as:
August to September - Number Sense and Place Value
We reviewed some basic concepts from Grade 3 and learned some new concepts. Using words, pictures and place value charts, we were able to represent numbers in many different ways. We used rounding to help us estimate amounts and we also practiced adding and subtracting numbers.
- repeated addition (example: 6x4 = 6+6+6+6
- equal groups (example: 6x4 = 6 groups of 4)
- doubling (example: 6x2=6+6)
- Adding on (example: 6x6=6x5+6)
- Subtracting from easy number (6x4= 6x5-6)
