0 of 12 concepts ready to learn · Markdown, for your AI

1. Geometry · Recognize and describe polygons (up to 8 sides), triangles, and quadrilaterals (rhombuses, rectangles, and squares) based on the number of sides and the presence or absence of square corner

1. Angles in triangles (age 7+): Recognise and draw shapes having specified attributes (e.g. a given number of angles or equal faces); identify triangles, quadrilaterals, pentagons, hexagons, and cubes
2. Understanding angles (age 8+): Understand that shapes in different categories may share attributes defining a larger category; classify quadrilaterals (rhombuses, rectangles, squares) and draw examples of quadrilaterals not in those subcategories

2. Measurement · Estimate and measure liquid volumes and masses of objects using liters (l), grams (g), and kilograms (kg).

1. Measuring Liquids & Masses: Measure and estimate liquid volumes and masses of objects using grams, kilograms, and litres; solve one-step word problems involving mass or volume

3. Measurement · Tell and write time to the nearest minute; measure time intervals in minutes (within 90 minutes.)

1. Numbers on a number line: Solve word problems involving elapsed time by adding and subtracting time intervals in minutes, including using a number line
2. Estimating answers (age 7+): Estimate and read time with increasing accuracy to the nearest minute; record and compare time in terms of seconds, minutes, and hours

4. Data Analysis · For a given or collected set of data, create a scaled (one-to-many) picture graph and scaled bar graph to represent a data set with several categories.

1. Picture & Bar Graphs: Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories; solve put-together, take-apart, and compare problems using information presented in a bar graph

5. Operations with Numbers: Fractions · Explain equivalence and compare fractions by reasoning about their size using visual fraction models and number lines.

1. Comparing fractions (age 8+): Compare two fractions with the same numerator or the same denominator by reasoning about size; record comparisons with >, =, or < symbols
2. Equivalent fractions: Recognise and show, using diagrams, equivalent fractions with small denominators
3. Equivalent fractions on a number line: Understand two fractions as equivalent if they are the same size or the same point on a number line; recognise and show families of common equivalent fractions using diagrams
4. Fractions on a number line: Recognise and use fractions as numbers: place unit fractions and non-unit fractions with small denominators on a number line

6. Operations and Algebraic Thinking · Use strategies based on properties and patterns of multiplication to demonstrate fluency with multiplication and division within 100.

1. Fluent multiplication and division facts: Fluently multiply and divide within 100 using strategies such as the relationship between multiplication and division
2. Fluent adding and subtracting within 100: Fluently add and subtract within 100 using strategies based on place value, properties of operations, and the relationship between addition and subtraction
