Estimating and measuring capacity

Today Bluebirds enjoyed a practical lesson, which took place on the playground, involving lots of water!

Mrs Parry challenged the children to estimate amounts of water and then use the measuring jugs and cylinders to see how accurate they were. This gave the children great experience in reading different scales and calculating various increments.

Measuring mass!

Today, Bluebirds began their new topic in Maths. They discussed different types of scales and familiarised themselves with the language such as grams, kilograms, heavier than and lighter than. The children selected two items to weigh and found which one was the heaviest/lightest. The children looked at a variety of scales with different intervals and practised calculating how much each increment was worth.

Racing in seconds

Bluebirds have been mastering their time-telling skills this week. Today they have been working on seconds and solving tricky problems which required them to conver seconds and minutes.

To begin the lesson, the children used stopwatches to time their friends running. Then they ordered the time in seconds from fastest to slowest.

Telling the time perseverance

Today, Bluebirds have been persevering with telling the time this week and today have been calculating the 24 hour clock. Children solved times using different methods as they found calculating minutes to the hour challenging.

Huey said “I solved the question by seeing that 40 and 20 go together as it is a number bond to sixty so I know that 10.40 am was also twenty minutes until 11 o’clock.

Sophia said “I know the numbers are in five. Knute intervals so I counted in fives around the numbers to calculate there was 20 minutes left until it was 11 o’clock.

Evie thought how to explain the question to her partner and decided to support her by drawing a number line to find the difference between 40 and 60.

Division skills

Yesterday, Bluebirds applied their division skills to solve reasoning and problem solving questions. They practised explaining their thinking.

Today, Bluebirds have been dividing two digit numbers with remainders. To begin the lesson, they were given 13 lollipop sticks to make into a square (so divide into groups of four) and afterwards 38 sticks to make into triangles (so divide into groups of three). The children progressed on to using number lines to subtract the divisor.

Dividing a two digit number

After working on multiplying two digit numbers, Bluebirds moved on to dividing them. Mrs Parry displayed a picture problem on the board so children could work together and discuss methods they could use to calculate the answer.

Sam and Charles share 68 sweets equally among themselves. How many sweets will each person get?

The children discovered they had used lots of different ways to work out their answers (see our photos!) so they shared their methods together as a whole class and talked about which were the most efficient ways. Then the class carried on calculating more division problems ushttp://year3.bellsfarm.org/wp-admin/options-reading.phping the equipment and representing what they had made using a part/part/whole model, alongside their written calculations.

Good work Bluebirds! We saw plenty of active listening, concentration and lots of children were working well together.

Subitising – don’t count them!

Bluebirds enjoyed a new activity today when they turned their hand to subitising. To practise recognising “the look of a number” by looking at a representation of dots either looking for patterns or groups of smaller numbers without physically counting each one. The children raced their partners for extra fun! The children attempted to name the amount in four seconds, then three seconds and finally two seconds! There was no time for actual counting!
