Addition and Subtraction Facts
In Stage 1 we learn that addition and subtraction are related. We know that if we have an addition number sentence, we can use the same numbers to make another addition number sentence and TWO subtraction sentences. We used dice to find an addition number sentence, then recorded the related number facts on christmas presents. We divided our presents into 4 quarters, so we had 4 chances to practise our maths skills.

Icecream Addition!
In Stage 1 we begin to investigate different ways to add one and two digit numbers. If we know how many tens and ones are in a number, we can use trading to help us in our adding. After a very busy lesson practising our trading skills, 1/2 Goulder got to show their understanding by building an icecream addition problem! We had a different number on each scoop of icecream, which we had to represent using dens blocks. We then used our trading skills to swap 10 of the unit blocks for 1 tens block and counted how many we had altogether. We learnt a lot about trading, and our icecreams looked delicious!

Snowman Construction Company
Now that our work samples are all finished, we've decided to start some fun maths activities with a Christmas theme! Our first challenge was to build a snowman with only $5 to spend. Students were given a price list from the Snowman Construction Company and $5 in coins. They created a shopping list and pasted on the correct amount by adding coins to create the total cost. In the next lesson, we got to buy our materials from the shop, run by three Stage 2 helpers. When we had purchased all the materials we needed, we pasted them onto a sheet of paper and built our snowmen!

mass
When we measure mass, we are measuring how much an object weighs. In Stage 1 we learn how to use equal arm balance scales and measure mass using nonstandard units such as cubes, dominoes or counters. We also learn how to compare the mass of different objects and order them from lightest to heaviest.
multiplication
When we use multiplication we are talking about groups of objects. Students in Stage 1 learn how to solve multiplication problems using concrete materials such as counters and lollies, and by drawing groups and arrays. We learn to write multiplication problems in different ways, including as repeated addition.
Addition
All students in Stage 1 should know their friends of 10  these are ways to make 10 using 2 numbers, eg 1+9, 2+8. Students should be able to use a variety of strategies to solve addition problems, including word problems. Here are some activities Stage 1 students have done in Term 4 to practise these skills.
money
Stage 1 students need to be able to identify coins, add the value of coins, and find different ways to make the same amount. In Year 2, we even begin to work out how much change we would get if we used a higher value coin to pay. If you have a student in Stage 1, they should be very helpful whenever you go shopping!

length
nonstandard units
Stage 1 students begin learning about length by measuring using nonstandard units. These can be classroom objects such as dominoes, counters, dice or unifix cubes  but only 1 type of object can be used at a time. We also use shapes for measuring, but must make sure that the shapes are all the same size. Here are some photos of 1 Hangan measuring length using shapes.
standard units
Stage 1 students use centimetres and metres when using formal units for measuring. We learnt that there are 100cm in 1m. 1/2 Goulder made their own rulers to help them understand what a cm looks like, and used their rulers for measuring. Don't forget to use your rulers at home as well.
collecting data
This week, 1/2 Goulder went on a Dinosaur Hunt! We used tally marks to record the number of each type of dinosaur we found. We then totalled our results to see how many dinosaurs we had found altogether. We used the information to create a bar chart and discussed the information presented.
volume
When we measure how much space a 3D shape takes up, we call this volume. Year 1 students have been building models using cubes and talking about the volume of the shape  to find the volume we just have to count how many cubes there are!
Year 2 students had an extra challenge  to build a tower with a volume of 18 cubic centimetres. 
area
Area is measuring how much space is inside a 2D shape. In Stage 1 we use different nonstandard units to measure area. We are some examples of how we can use squares to measure area.
fractions
Calendars
Stage 1 students need to be able to read information from a calendar. Here are 1 Hangan making their own calendars!
number lines
shape activities
2 Palamara completed rotations working on different 2D and 3D shape activities. Here are some photos of what they got up to!
Length
Here are some photos of 1 Hangan measuring the length of a table. Why do you think they are using rulers with different animals on them?
symmetry
Take a look at some of our symmetrical pictures and patterns!
Subtraction games
We have been focusing on counting backwards, finding 1 less, and subtracting this term. Here are some of the games we have enjoyed playing.
COIn recognition game
You can practise your coin recognition skills at home with this fun game. You need at least 2 people to play. 1 person takes a coin and hides it in their hand. The other person has to guess what the coin is by asking yes or no questions. For example,
"Is the coin silver?" "Is the coin round?" "Does the coin have a platypus on it?" "Is the coin a dodecagon?" (Do you remember what a dodecagon is!?) After 3 questions, the partner must try to guess what the coin is. If they are correct, they swap roles. Maybe if you are really good you'll be allowed to keep the coin! Have fun playing! 
Funny face shopping
At the end of term 2 we began to look at money. We learnt the different types of coins, and how to add coins to make different amounts. Then we got to test our new skills by going shopping! We had a shopping list and had to buy the ingredients with the correct coins. For Year 2 students this activity was made more difficult as we didn't have the coins we needed in our purse! We had to work out the total cost of ingredients and then see if we could use the coins we did have to make this amount. When we were ready, we went shopping and bought the ingredients from the shopkeepers, then went back to our desks to create our funny face biscuits.

Fairy Bread Fractions
Olivia about to eat half of her bread!
We have been learning about fractions in a very tasty way! We made fairy bread and demonstrated how to cut a whole piece of bread into halves and quarters. We found there are different ways to cut a square slice of bread into halves and quarters.
Some students extended their learning by using their knowledge of fractions to divide groups of lollies into halves and quarters.
Some students extended their learning by using their knowledge of fractions to divide groups of lollies into halves and quarters.
Area
As part of our work in measurement, we have been investigating area. We learnt that area is measuring how much space is inside a 2D shape (or how much space the shape takes up!) As we have been studying transport, we measured the area of transport shapes (although we don't think the car will get very far with square wheels!)
