How will you celebrate Pi day in your classroom? Pi day lands on a Saturday this year 2020 but we plan to celebrate a day early on Friday March 13th. Here are some ideas including a free download from NumberLoving.
Beauty of Pi Use this video below to demonstrate the beauty of Pi or download the app by Fraser McKay and Chris Smith from their PiWire site here to explore Pi and other numbers visually.
One Million Digits of Pi Display as a list here or a rap video by AsapScience for just the first 100 digits in the video below.
Pi Day Dingbats These are great for form time; say what you see! Download this PowerPoint presentation shared by Lloyd here.
Pi Day Puzzle Free Download Two different puzzle styles, one is a straight forward pi-doku based on Sudoku but only using the digits 314 and the second is a reasoning puzzle similar to GCSE area/percentage question with no dimensions.
Our fourth freebie this week is a series of four maths picto-puzzles each of varying difficulty.
Here is an example page;
They include addition, subtraction puzzles and multiplication. Challenge your students to find the value of each Valentines symbol, watch out for valentine’s symbols within symbols on the more challenging picto-puzzle 4 and 5.
The full resource can be downloaded here by clicking the link below.
This free download includes 4 different Valentine picto-puzzles which can be displayed or printed as worksheets, with solutions. Ideal for a quick starter or plenary. You should also check out our premium Valentine bundle.

Another quick NumberLoving freebie Maths activity for the week of love, leading up to Valentine’s Day. Definitely suitable for GCSE 9-1 Maths and has plenty of challenge (Pythagoras, multi-step, area of parts of circles, area of sectors and segments).
There are five different hearts and pupils are asked to find the area and perimeter of the heart. The hearts are made up of triangles and two semi-circles or the more challenging heart (heart 5) requires pupils to calculate the area of two identical major circle segments.
Take a closer look at worksheet five for the extra challenge, suitable starter or plenary for Higher GCSE students.
Download the full free resource via the link below; this includes five different hearts of varying challenge that can be printed as worksheets (or displayed) and includes the solutions!
I was recently asked for numeracy ideas which could be delivered to all departments across the curriculum as a hit of numeracy.
Below I’ve listed the ideas that came to mind.
Participation Pie Charts
When completing group work, as the pupils to draw or use an instant pie chart, where each colour represents each member of the group. They then represent their participation through proportions.
Check out our post Instant Graphs for instructions on how to make instant pie charts.
Where is the Maths?
Display subject related photos such as sprinters crossing the finish line in PE, Mondrian photos in Art, or a freeze frame from a Simpson’s episode (any they have a lot of maths) and pose the questions “where is the maths”?
Is …… a Mathematician?
Again use a subject related picture such as a picture of Heston for Food Technology is displayed along with the question “is Heston a Mathematician”?
Organising & Sorting
Ask pupils to organise or sort items, products, topics, keywords into groups. Use hula hoops to create venn diagrams. Ask pupils to justify their categories.
Ask Mathematical Questions
Is there a pattern?
Can you predict what is next?
What is your hypothesis?
What’s the same? What’s different?
Scrabble your Key words
I love this idea from Mr Collin’s check it out here. Ask pupils to create a list of topic keywords and using the scrabble value for each letter they find the total sum of each word. The student who find a topic related word with the highest score wins.
