Classifying Triangles Using Sides
In this geometry worksheet, students answer 8 fill in the blank questions where they must examine 5 different complex geometric figures to classify triangles.
Curated OER
Tiling Tessellations
Students explore tessellations. For this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

Card House
Mathematics is stronger than a card house. Pupils watch a video of the beginning of the building of a triangular card house. Scholars come up with questions they wonder about from the video and ask for more information to arrive at an...
Bowland
Security Camera
Take an overall view of percentages. Pupils determine whether a shop owner's claim is correct about what percent of his shop is viewable from the installed security camera. Learners try to find whether there is a better location for the...
