Part of: [New Brunswick: Mathematics](https://ai.page/roadmap/ca-nb.md)

Goal: New Brunswick curriculum: Mathematics, Grade 2

## 1. Statistics and Probability

- [Measuring & Plotting Lengths](https://ai.page/c/measuring-and-plotting-lengths/index.md): Generate measurement data by measuring lengths to the nearest whole unit and display the data on a line plot

## 2. Shape and Space

- [2-D shapes (age 7+)](https://ai.page/c/2-d-shapes-age-7/index.md): Draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them
- [Building with 3-D Shapes](https://ai.page/c/building-with-3-d-shapes/index.md): Compose three-dimensional shapes (cubes, right rectangular prisms, right circular cones, right circular cylinders) and create composite shapes; build new shapes from component shapes
- [Sorting 2-D and 3-D shapes](https://ai.page/c/sorting-2-d-and-3-d-shapes/index.md): Compare and sort common 2-D and 3-D shapes and everyday objects by their properties
- [Measuring with different units](https://ai.page/c/measuring-with-different-units/index.md): Measure the length of an object using two different length units and describe how the measurements relate to the size of the unit chosen
- [Measuring mass and weight](https://ai.page/c/measuring-mass-and-weight/index.md): Measure and begin to record mass/weight using non-standard and standard units
- [Days, Weeks, Months & Years](https://ai.page/c/days-weeks-months-and-years/index.md): Recognise and use language relating to dates, including days of the week, weeks, months, and years

## 3. Patterns and Relations

- [Patterns & Sequences](https://ai.page/c/patterns-and-sequences/index.md): Order and arrange combinations of mathematical objects in patterns and sequences

## 4. Number

- [Adding two two-digit numbers](https://ai.page/c/adding-two-two-digit-numbers/index.md): Add and subtract two two-digit numbers using concrete objects, pictorial representations, and mental methods
- [Mental and written addition and subtraction](https://ai.page/c/mental-and-written-addition-and-subtraction/index.md): Solve addition and subtraction problems using mental and written methods, including problems involving numbers, quantities, and measures
- [Adding numbers](https://ai.page/c/adding-numbers/index.md): Add up to four two-digit numbers using strategies based on place value and properties of operations
- [The multiples of 100](https://ai.page/c/the-multiples-of-100/index.md): Understand that the multiples of 100 (100–900) each represent a number of hundreds with 0 tens and 0 ones
- [Estimating by rounding](https://ai.page/c/estimating-by-rounding/index.md): Estimate the answer to a calculation and use inverse operations to check answers; apply to increasingly large numbers using rounding and inverse reasoning
- [Rote counting to 100](https://ai.page/c/rote-counting-to-100/index.md): Rote count forwards and backwards from 0 to 100, beginning from 0, 1, or any given number, by ones
- [Number Words to 100](https://ai.page/c/number-words-to-100/index.md): Read and write numbers to at least 100 in words
