Numeracy

We have been learning to tell the time using O' Clock on analog and digital clocks. Today, we took our learning outside and used natural resources to represent the big and small hand on the clock!

We played the game 'Switch Spots' to help us understand how to find the missing addend. We worked in pairs and used lots of concrete resources including dinosaurs, bears and spiders. This is a really tricky concept, but we were able to use the counting on strategy to help us find the answers!

We have been learning to measure length using non-standard units. On the play tray, there were lots of different wriggly worms, some were very short and some were very long. When measuring the worms, the children made sure they were very precise. Once the cubes covered the whole length of the worm, they counted the cubes to find out how long each worm was!

We have been learning that addition is commutative, which means you can change the positive of the addends and the answer will still be the same. The children used flip-flops to help them understand that if you swap the two shoes around, the answer will still be the same!

Addition using a Numberline

The children were learning a new addition strategy in numeracy this week and it was how to use a number line.

 

We Learned that:

 

1. The first number in the addition sum is the number you find on the number line.

2. The second number is the number of hops you make on the number line.

3. The number you land on is the answer to the question.

Elf Call Problem Solving. Strategy - Draw a Picture

Today, we had a Christmas problem to solve called 'Elf Call'. The children needed to listen carefully to each question and use their knowledge of counting in 2s to find the answer!

Heavier Than, Lighter Than!

In today's lesson, children were comparing the weight of classroom objects. We made predictions and then investigated to see which was heavier, which was lighter or if they weighed the same amount!

Adding Three Numbers

We used Numicon to help us add three numbers together this week, and it was great to see some children using our 'counting on' strategy to help them find the answer quicker!

We enjoyed playing a game called 'Bunny Ears' to help us quickly recall our double facts to 10. We then used concrete resources like our ladybirds and spots to recall our double facts to 20!

Miss Barbour brought some coat hangers, string, and plastic cups into school today and worked with us to make our very own weighing scales! We brought our scales outside and compared the weight of natural materials including sticks, stones, grass and sand. Before putting materials into the cups, we made predictions about the weight of the object and what this would look like on the scales. We found that the scales dropped down when something heavy went into the cup, the cup with the lighter material in it went up and if both cups were at the same height then this means both objects are the same weight and the scales are balanced!

We had a spooky problem to solve this week in Primary 2. Winnie the witch is a little bit lazy and asked Miss Barbour to wash her stripy socks for her. The boys and girls in our class helped hang six socks out on the washing line to dry and found out that the number six could be sorted into three pairs. We then tried to put thirteen socks into pairs, but there was a problem. We figured out that thirteen is an odd number so there was a sock left over! 

2D Shape Carroll Diagram

Children have been learning all about 2D shapes during topic maths lessons this term. We have learned the names of 2D shapes, have found 2D shapes in everyday items, and looked at the properties of 2D shapes. Today, the children were introduced to Carroll Diagrams and learned how to sort 2D shapes based on their properties using the criteria '4-sided shapes & Not 4-sided shapes'. Next time, I think we could challenge ourselves to sort data by two different criteria! Well done everyone!

In problem-solving, the children continued to learn about ordinal numbers but this time they were working from 1st to 10th place. In small groups, children were given clipboards with animals on them. They needed to hunt for these animals around the school, count what position they were in the line, and find/colour the corresponding ordinal number. We love 'Write the Room' activities and can't wait to see the other fun activities Miss Barbour has planned in Primary 2!

We have been learning about ordinal numbers in problem-solving and we soon realised that we use these numbers all the time, especially when we are discussing the date, our birthdays, and getting into line order for outdoor play! To consolidate our learning we thought it would be a great idea to take part in a car race to practise ordering ordinal numbers in a practical way. We each chose a car and raced it on the track, we then worked together to order our cars from 1st to 5th place!

We are revising the names and properties of 2D shapes in Primary 2 and today, we decided to go on a shape hunt around our school grounds. We found lots of 2D shapes everywhere we looked as you can see from our photos!

Recognising and Ordering Numbers to 10!

We played a game called 'Switch Spots' where we had to identify the number on a ten frame and then find/colour the matching number on our clipboard. This was such a fun way to revise our numbers to ten and we can't wait to play the other versions of this game!
