Searching for Angles and Lines

How much sugar is in one bottle? Pupils use double number line diagrams to determine the amount of sugar in a 1L bottle of cola. The teacher leads a discussion on ways that double number lines can be of assistance in solving a...

Budding artists or mathematicians read about,and then draw, two very different shapes. Geometric and organic 2-D shapes are defined. Learners use the definitions to draw examples of each.

Scholars learn how to determine the area of compound shapes by finding the areas of the basic shapes that make it up. Pupils find the areas by adding areas together or subtracting them.

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging learners to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Challenge young mathematicians' understanding of symmetry. Provided with images of different shapes, letters, and national flags, students are tasked with identifying the lines of symmetry and order of rotational symmetry...

Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, students apply this new knowledge to...

Systems of parallel lines have no solution. Pupils work examples to discover that lines with the same slope and different y-intercepts are parallel. The 27th segment of 33 uses this discovery to develop a proof, and the class determines...

Is the graph of the equation a function? Use the vertical line test to answer this question. The definition states that the vertical line can pass through the graph of the line no more than one time. The teacher demonstrates exactly what...

Explore line graphs and their characteristics through an interactive lesson. Scholars follow a set of directions to plot data on a line graph. They then answer questions about the type of variables, minimum and maximum values, and...

Graph a set of numbers on a number line by placing a dot on the number line to represent each number in the given set.
