Today was all about pairs of numbers that make 10.

Recording a number sentence to 10.

Good quick work everyone.

The 'whacker' game is a favourite!

Marking a partner's work.

Making ten on the calculator.  We can see a pattern.

See you next term everyone!

Reflections from Room 18 ALiM students

Counting in groups of tens

Stella is using the numicon to make groups of ten

Luna says "7 tens is 70"

Kate knows that 2 tens is 20

6 groups of 10 is sixty

Then we used our tens knowledge to play Mrs Culling's 'groups of 10' twister game.  We discovered that all the girls in this group are right handed.

What a tangle!

Holly loves the 'friends of ten' app on the i-pad.

The 'whacker' game. 

One person 'whacks a number and the other person has to 'whack' the other number that will make 10.

Student Reflections:

Friday 6 September

Last week was our final week of Senior ALiM lessons and now we are into the testing to see what gains the students have made.  Unfortunately, there was no blog last week as the school internet was not working.

The Nice or Nasty game.

Great place value practice.

After we had played the 'standard' Nice or Nasty game, we tried lots of different variations:

• lowest number
• give away your third roll
• use a decimal point
• closest to a target number
• a six digit number
• play as a team

Working as a team to make the basic fact bubble puzzle.

Everyone made up their own problem for people to practice our subtracting trick.  When there are lots of zeros, subtract one from each number and then you still get the same difference.  Much easier! (40000-5378 as 39999-5377)

Place value pebbles!

We gave each colour a value.  Yellow = ten thousands, orange=thousands, purple = hundreds, red = tens and green = ones. 

Tuesday 3 September

Teen number match up

Quick images - how many on the card?

Subtraction from 10

There were 10 monkeys in the tree and one went away to have a banana.  How many monkeys are in the tree now?

Kate is writing a number sentence.

Adding one, using cards.

Counting in fives.

Tuesday 27 August: Junior ALiM

Today we experimented using some different place value equipment to make our two digit number.  We used sticks, animal strips, place value blocks and a place value abacus.  On the abacus we could see that where we placed the rings determined a number's total value.  If we put 5 rings in the ones place it made 5, but if we put the 5 rings in the tens place, then it made 50.  Mrs Culling was very very impressed at how we were able to make our numbers on the equipment so quickly. 

Luna's number: 2 tens and 0 ones

Stella's number

Holly's number

Kate's number.  We talked about that if Kate had to add 1 more to her number it would be 50.  Then there would be 5 rings in the tens place and 0 in the ones.

Adding 1 with the cards.

Ways to make ten with the animal strips.

Thinking of our rhyme helped us make 10 (5 and 5, swim and dive)

Kate made some more complicated number sentences.

We have 5 toes on each foot, so we used feet pictures to count in fives.  Who can see that counting in fives always ends in a 5 or a 0?

The ace card is one.  Holly adds 1 and 2.  This is quick practice of adding.  Everyone was very enthusiastic doing this ... it got noisy in the red room!

seven and three - time for tea!
