Week of Inspirational Maths, Day 2

Here is today's video which is about brain crossing.



What are the key messages in the video?


Number visuals:

1. Write the number that each visual represents on your number visuals handout.

2. What do you see in the number visuals? Do you notice anything interesting about the way numbers are shown? Share your findings with your group members and discuss them together.

3. Look for interesting patterns. You may find it useful to use colors to highlight them. Describe some of your findings and share with your group members.


Consecutive Numbers :

The number 12 can be written as a sum of consecutive numbers, 3 + 4 + 5 = 12. Another example of a consecutive number sum is 3 since 1 + 2 = 3. Can all numbers be written as sums of consecutive numbers? Can some consecutive number sums be written in more than one way?


Using the hundred chart circle three numbers in a row (horizontally) and add them. Try this with several sets of numbers. Do you see a pattern? Does your pattern work for every group of three consecutive numbers? Write a convincing argument.


Using the hundred chart circle four adjacent numbers to form a square. If you add the diagonals what do you think will happen? What does happen? Does this work for every group of numbers in this pattern? What do you wonder? Write a convincing argument.


Using the hundred chart circle four adjacent numbers to form a square. If you multiply the diagonals what do you think will happen? What does happen? Does this work for every group of numbers in this pattern? What do you wonder? Write a convincing argument.

Here is a full PDF of the activities for today.
