Final Maths PD with Jo Knox at Sherwood
Primary 22nd Here-Turi-Koka,
2018
Mathemagic
Take a
number between 2-9
Multiply it
by 9
Add digits
together
Add 6
Choose the
letter matched with.
Think of a
fruit beginning with that letter and write it down.
Just
kidding! Not banana!
Look in the
box behind you....
How do you make maths relevant?
Lots of incidental
linking to maths, eg. We need 4 groups and we’ve got 25 kids, how many in each
group? For our school trip we have a 1:6 ratio for parent help. How many
parents can we take? Mathemagic and games help chn with maths and they don’t
realise they are learning and practising.
Shared
sites
Solvemoji – algebra and problem
solving
Games is a
great way to practise as it’s fun, engaging and often incorporates a few
mathematical skills.
Game: Target
15, 287 – can use cards or dice on TV.
Doing it
with a buddy generates conversation and double checking.
We usually
set children set tasks eg. 1128 chn are going on a bus. Each bus carries this
many children. Solve it.
Everyday we
are using lots of estimation and maths in our own lives. Time getting ready in
the morning, cooking, petrol prices for car, online purchases, measurement of
house, clothes etc. Giving students open ended tasks or give the solution makes
students think.
Sometimes take the numbers out first, so chn
figure out the context, just like we do in real life. PROBLEM POSING – HIGHER ORDER
THINKING OF CREATING INSTEAD OF JUST APPLYING.
____
children are going on a trip on the bus. Each bus can carry ____ students. How
many buses are needed? Or ‘We need buses for next week. How many do we need?”
Start them there.
There are
125 sheep and 5 dogs. How old was the shepherd? (Chn will give answers to this
eg. 125 + 5 = 130 so he’s 130 years old, or 125 divided by 5 so he must be 25).
Try on Room 12! See what they say.
Monthly
expenses graph with percentages – what do they notice first?
Monthly
expenses chart – What do you notice about Tina’s life? No car? What could
other be? Cost of living etc. What other questions would they want to ask?
Minions
Worksheet – Pick Stuart or Bob for if you were born here, or overseas. Then
colour the dungarees if you like diff flavours of ice-cream, drinks etc.
Can easily
sort the data visually to find out information with your class. What questions
would you like to ask and find out info on?
Who was
born in NZ? Where were other people born?
Who likes
choc ice cream? What is the most popular icecream in the class? Etc.
Use a variety of maths problems.
My garage
is big. If I have 5 cars, and 2 are parked outside, how many are in? Closed
question.
Or
How many
different ways can I park 5 cars?
Procedural vs. Rich
Procedural - definite numbers, limited context, right or
wrong answer, one step problem.
Rich – less numbers given (eg. Here is the giant’s
handprint, how tall is the giant?), lots of answers and outcomes, trial and
error, more conversation generated through collaboration, negotiating,
How to create open questions: Work backwards.
The Smith
family children are aged 3, 8, 9, 10 and 15. What is there average age?
Vs.
There are 5
children in the Smith Family. There average age is 9. How old might the
children be?
Finished with a rich task of making a triangle tetrahedron with 6 kebab sticks and rubber bands. Started with some real life data on ancient pyramids, then made our own. How can we expand it by into size 2? Put all 4 triangles together and join. How many sticks used now? How many would be used to expand it to size 3? Size 4? How about size 10? Lots of discussion and trial and error with us as adults! Pretty fun and challenging way to do maths.
Excellent
course!
