How Cactus π sheets work

At Home

Despite the myriad of online resources, many mathematical concepts are best taught and reinforced with paper and pencil techniques. Cactus π worksheets provide instant assessment for you and your child without needing to mark each question. Most activities take between 20 and 30 minutes, ideal for reinforcing key concepts, keeping skills sharp over the school holidays, revising for exams or extending the more able child.

Most of the worksheets involve solving a series of mathematical problems to find the punch line to a cheesy joke. Students love finding out what the punch line is. Mistakes in the student’s problem solving can quickly be identified by spotting a spelling mistake in the punch line.

The packs have been organised into Year Groups and Topics. Simply select the Year Group and Topic from the drop down menus.
