Thursday 30th July - Number bonds and related

Pre task - explore own ability to subitise


Starting Game - adding to 20, 50 etc.
Try as a board game with battleship like set up. explorers split amount of counters into 3 sections and check who has won
Extend by using written sheet and collecting scores to make Leaderboard

Check ability to subitise using different cards like those shown on the right.  See if we can get them to discuss anything they found out or help or coach each other.  See how they think someone might test this skill with a group.

Number Bonds to nine and ten
Using the split 3 way board, how many different ways are there to split 9 into different numbers.  Are there more ways of splitting 10?  How does it change if you can use zero?
How many different ways can you find?  How could you list them?  What is the best arrangement of 9 counters to make it easiest to subitise?  It would be good to carousel this activity but I don't know if that will work.  Need to be ready to organise this in some way.

Dice game - Dicey Operations
Add up to 100 or 1000.  We can use this game by Nrich.  Model this as a competition with two people or anyone else who volunteers.  Throw a dice and put the result in one of the boxes.  Do this 8 more times and get three 3 digit numbers and see what they add up to.  Get explorers to suggest techniques for getting closer to the right number.




Hidato and Beehive Hidato - Consecutive numbers - finding the path
Start this by getting them to take it in turns to place a number.  If we can't go, take back a few steps and try again.  What is the difference in this challenge between the square and hexagonal grids?

Kakuro
This is also a game involving number bonds that explorers can try
I can create a scaffolded example starting with one line etc.

Adding odd and even
What are odd and even numbers?  What happens when you add odd and even numbers?  Can you predict if the answer will be odd or even?

Finding consecutive sums - 
Introduce project to find consecutive sums of different numbers. Tick them off on the sheet.

End game - Coloured matching nim game.  What could be done to help with this game. Elicit too many to subitise.  Try estimating.  How many needed to win different colours.  Add up scores and say first to 50 wins

Organisation - I would like to create a way of tracking progress, ideas or interest.  It could be a small sheet with the activities on them and smiley faces.  It could also be a laminated sheet that people stick stars on or something.  I need to make sure that I record some feedback.
Also getting them to think of next steps for some of their activities would be good.
Th passport idea would be great for these sessions too.
Take home tasks could be linked to the activities in the session and there can be a card to take home with challenges or games and some thing to come back and tell us.

Unfortunately it's 9 tonight and still a few things to get ready for the activities. Much of it may need to wait but it would be great to make some progress with at least one.
