Amelia Showing us her trick for 7 time tables.

This is a trick to learning 7 time tables!  Amelia showed this to us!1

Junior ALiM children were busy today!

As the children came into the red room, they had to read the numbers.

Then everyone chose a number and made it with the place value equipment.

Math Adventures: find a number on the 100 board

Math Adventures: what is the number before or after ...

We used the numicon as we sang our bonds to ten song.

We like the 'Friends of Ten' ipad game

2 and what makes 10?

Roll a fact board game.  It is like connect four.

How many dots?  How do you know?

MATHS WEEK CHALLENGES
This week is Maths week.  For every correct question we earned 20 math dollars.  Mrs Culling said if we got $250.00, we'd earn a chocolate fish.
There were questions about:

• cupcakes
• train timetables
• reading the time
• magic squares
• shapes
• New Zealand food, money and climate
• powers of numbers
• what went wrong (some badly spelt road signs and markings)
• And we now know that a French mathematician called Blaise Pascal invented the calculator.  Thanks Mr Pascal - it was a tool that was used quite a bit in our session today!

For homework Room 17 are looking at Mrs Culling's cell phone plan.  Mrs C didn't think that she was getting a good deal and has now changed to a different plan.  Has she done the right thing?
Some things that we discussed were: how many texts a day did it average out as and how many cents per text was it costing.  

For Math Week, Mrs Longman has challenged the school with this:

12+3-4+5+67+8+9=100

Can you come up with one other representation of 100 with 9 digits in the right order and mathematical operations in between. (I've heard of at least 3 possible solutions so far!)

Giorgia and Jason are trying various calculations on Mr Pascal's calculator in order to see if Mrs Culling was right to change her cell phone plan.

I think the person who painted this road marking needs to go back to school!

Brooke's haul of chocolate fish!  2 fish for being first to answer the 'Essential Resources' questions, 1 for being her group's e-ako champion and 1 for getting $250 math week dollars.  Poor Mrs Culling will be broke if Brooke keeps this up!

 Today we started learning a new game called 11,111.
It involves multiples of ten.
It is a little like the game 'go fish'.  The first person to make 11,111 is the winner!

We are estimating the number of animals that are in the jar.  We took out a set of ten at a time and Mrs Culling allowed us to change our estimates.  Things that helped us estimate were: taking out groups of ten, seeing what fraction had been removed or was left in the jar, looking at the layers of animals and multiplying, knowing that the container that the animals are usually in has a total of 75 animals and comparing the animals to the marbles we estimated last week.

Some people are on track to have 2000 points in the next few weeks, some need to get busy!

 This is a new game called snatch

Friday 2 August

 

 We are talking about basic facts.  
At the moment we are concentrating on x9.  Some people drew long-winded pictures to represent groups of nine on their thinkboards, so we looked on our equipment table and decided on some efficient ways to make groups of nine!

 Amy used the numicon to show the number sentence seven groups of eight make 56.

Amelia is doing a basic facts exercise on e-ako.

Quick images.  How many dots do you see?  Explain how you saw the dots grouped.

A basic fact that trips people up ... 8+3.  If we know that 8 and 2 make 10, then it must be one more.

Georgia uses sticks to help her record the family of facts for 8+9.

 Our tricky question of the day!
Well done Monique and Giorgia who were quick to solve this.  Room 18 students have taken this away to ponder as a couple of people thought that it only took George 3 minutes to bike home.  Brooke said that this was unrealistic! 

Funnily, it was our very own George that had the best estimate in the beginning.  He said 20-30 minutes to visit Grandma.  (We wrote our estimates on the post it note before solving the problem - what do you think of the estimate in the photo?).

Jason and Monique add the dots on the two tens frames instantly!

Now they said how many more dots are needed to make 10, 20, 50 or 100.

Hardworking ALiM students!  Way to go Amy and George.


A FINAL REMINDER FROM MRS CULLING
You should now be working towards your 2000 e-ako points.

Next week Mrs Culling is away on Thursday, so I won't see you all till Friday.  Enjoy the snow on Wednesday!
