This week in one our math investigations we were challenged to find all possible combinations available from a different number of variables.
To get started we began the investigation by seeing if we could find all the possible ‘triple header’ ice-creams you could make with 3 flavours. Using mathematical strategies of prediction, making a model and/or draw a mathematical diagram , students chose to work individually or collaboratively to solve the problem. It was great to see the variety of strategies being used and to hear the powerful mathematical thinking happening throughout the lesson.
Now, in the past we might have left this lesson and move on to another topic, but as mathematicians often ask the ‘what if’ question we were introduced to Mr. Whippy and his desire to take out the competition with his ‘Quadruple header’ ice creams using four unique flavours.
This challenge saw our students begin to really think (I’m sure I I could hear all the brains working) and it was really powerful,to,see and hear a variety of mathematical strategies being used by our students. Making connections with the previous challenge; thinking about similar problems; looking for patterns – these strategies enabled almost every member of the investigation team find the solution.
We would love to hear about the strategies you used to solve this challenge. Please click on the ‘comment button’ and share how you solved the Mr. Whippy challenge.
We see numbers everywhere…speed signs, tv channels, calendars and house numbers. Just about everywhere you look you will see numbers of some kind.
Stop for a moment and look around. What numbers can you see?
Being able to read, make and understand numbers is a really important skill we all need to master.
In POD 2 this term we are working in small groups to build our number skills. One area we are working on is being able to pull a number apart in different ways. Check out the pictures below which show how 2 digit numbers can be pulled apart into ‘tens’ and ‘ones’.
Can you think of a number which you could pull apart to show the value of each digit? Please leave a comment and share your favourite number and how you would break it down to show the value of each digit.
Have a go at this number quiz.

This week a group of student in POD 2 have been exploring maths through bugs!
Did you know ants are a great tool for counting by 3s and 6s and spiders are excellent for counting by 8s?
We have been working on our strategies to help us solve problems and have focussed on drawing diagrams, making models and working backward to solve problems. We used number lines to help us count as well.
One thing some students noticed was the pattern of 4, 8, 2, 6, 0 when counting by 4s.
