Year 2 maths worksheet: 3 sided shapes

A pinboard is a great way to investigate shapes.

This may be made by nailing panel pins or small nails into a piece of plywood approximately 24cm × 24cm.

Cut out the plywood and mark a grid of lines at 2cm intervals in both directions across the plywood. Tap in the pins at the points where the lines of the grid meet. Leave enough of the pins protruding to accommodate elastic bands.

This page looks at how many different 3-sided shapes can be made. The results can be drawn onto the page of ‘pinboards’. When investigating this it is important  to talk about the shapes and ask questions such as:

what counts as a triangle?

how many different kinds of triangle have you made?

Are some the same, but just a different way round?

etc

Teacher Awards

At the start of a new half term it’s good to know that some of the very best teachers in the country have been recognised for their efforts. Eight teachers were named at the reward ceremony in London, hosted by Lenny Henry and attended by stars such as Emma Thompson, Henry Winkler and education secretary Michael Grove.

Kelly Steeples, a primary teacher from Ossett won the outstanding new teacher award for her amazing lessons incorporating dance and science.

Becky Newman won the award for best teaching assistant. She retook her Maths GCSE at the same time as helping in the maths department at Tendring Technology School, showing it is never too late to learn.

Perhaps the star of the show was Peter Jones who was given a lifetime award after getting over 50 nominations. He has been described as a ‘legend’ with a genius for innovative teaching, again using inventive drama to create outstanding lessons.

Well done to all the winners. As Emma Thompson said at the awards:

“Without great teachers we are not going to have a great society.’
