Math Games

4.GM.1.1

Measurement • Use appropriate scales, devices, and metric units for length, area, volume and capacity, weight (mass), temperature, angle, and time. • Convert between metric units, using whole numbers and commonly used decimals. • Use side or edge lengths to fi nd the perimeters and areas of rectangles, parallelograms, and triangles and the volumes of cuboids. • Interpret and use scales, timetables, and charts.

4.GM.1.2

Shape • Identify classes of two- and threedimensional shapes by their geometric properties. • Relate three-dimensional models to two-dimensional representations, and vice versa.

4.GM.1.3

Position and orientation • Communicate and interpret locations and directions, using compass directions, distances, and grid references.

4.GM.1.4

Transformation • Use the invariant properties of fi gures and objects under transformations (refl ection, rotation, translation, or enlargement).

4.NA.1.1

Number strategies and knowledge • Use a range of multiplicative strategies when operating on whole numbers. • Understand addition and subtraction of fractions, decimals, and integers. • Find fractions, decimals, and percentages of amounts expressed as whole numbers, simple fractions, and decimals. • Apply simple linear proportions, including ordering fractions. • Know the equivalent decimal and percentage forms for everyday fractions. • Know the relative size and place value structure of positive and negative integers and decimals to three places.

4.NA.1.2

Equations and expressions • Form and solve simple linear equations.

4.NA.1.3

Patterns and relationships • Generalise properties of multiplication and division with whole numbers. • Use graphs, tables, and rules to describe linear relationships found in number and spatial patterns.

4.S.1.2

Statistical literacy • Evaluate statements made by others about the fi ndings of statistical investigations and probability activities.

4.S.1.3

Probability • Investigate situations that involve elements of chance by comparing experimental distributions with expectations from models of the possible outcomes, acknowledging variation and independence. • Use simple fractions and percentages to describe probabilities.
