Numeracy

Solving problems by acting them out

P5A have been using their problem solving and teamwork skills in Numeracy this week. They were tasked with making a range of displays using lollipop sticks. The children worked together to follow the instructions and solve each problem. 

Dividing and rounding using calculators

P5A have been practicing their division skills this week. Today they used calculators to divide three digit numbers. Some of the answers had numbers after the decimal point, so the children used their rounding skills to find the nearest whole numbers. They explored this using whiteboards, before trying questions in their books.

Dividing numbers using short division

This week P5 were working on using the short division method. They tried this on whiteboards, making groups of numbers with counters. The practical resources helped the children to visualise the problems. 

100 days of school

This week we celebrated 100 days of school. During the week we enjoyed a range of activities, such as mental maths challenges and a special 100 days homework. P5A took part in a challenge to see what they could achieve in 100 seconds. How many star jumps could they do? How many words could they read and write? How many sit ups could they do? They exceeded even their own expectations!

 

Learning to check answers using multiplication and division fact families

In numeracy today we revised our understanding of division facts and their links to multiplication. The children worked on matching division and multiplication fact families through games and group activities. 

Finding times before and after through bridging

P5A have been enjoying the topic of time in Numeracy. Today we worked on finding times before and after, for example 15 minutes after 3pm. Then we worked on ‘bridging the hour’, splitting the time up to help us to tell the time. We explored this together and then the children took part in a game of Bingo, in which they had to work out the times before and after a given time and find them on their cards.

Dividing by 10, 100 and 1000

We have been working on dividing in our Numeracy lessons and today we focused on different strategies for dividing by 10, 100 and 1000. The children worked on moving the digits using place value charts and then tried their own problem solving activity, matching the equations to answers.

WALT: Use varied division language to explore dividing into equal groups.

 

P5 have been exploring division this week in Numeracy. They tried it practically first, using counters to try division equations on their whiteboards. We discussed the importance of counting carefully to make equal groups. Our next step will be working on abstract equations to link multiplication and division facts. 

IZAK 9 Problem Solving

 

P5 have been focusing on the area of following patterns in our problem solving this term. We have used the IZAK 9 cubes to work out different patterns and complete the missing blocks. We used wonderful team working and decision making skills to solve the problems.

Properties and types of Triangles

 

We have been learning about different types of triangles this week. The pupils used different equipment in the classroom to create equilateral, scalene, isosceles and right angled triangles and correctly label them, thinking about what properties each type of triangle has.

Straight Lines

 

Today we were exploring vertical, horizontal and diagonal lines are and which lines different 2D shapes have in them by folding and highlighting the lines.

Multiplication Facts

 

We have been focusing on different ways to work out the answers to the 6,7,8 and 9 times tables using various strategies. P5 have been completing different activity based learning and outdoor learning activities to practise quick recall of the multiplication facts.

Area of Irregular Shapes

 

P5A have been drawing round various irregular shapes and using cm squares to count the area that the shapes cover.

 

 

Multiplication Facts

 

This week in numeracy we have been exploring multiplication facts, and using other known multiplication facts to solve answers we don’t know. The children competed a treasure hunt, looking for the correct answers to find the hidden clue.

Maths Week Ireland
 

P5 started off Maths Week with a bang by taking part in a live lesson that challenged them to solve a variety of problems. The problems were engaging and challenged the pupils to work together to come up with the answers, all while exploring different properties of shapes.

Problem Solving

 

P5 have been learning to use diagrams to help them with their problem solving and investigations this term. They used pictures and moved them around to physically solve the tricky problem. 
 

A farmer must transport a fox, a goose, and some grain across a river. She has a boat which can only carry herself and one other thing. If the farmer is not present, the fox will eat the goose. If the goose and the grain are left together alone, the goose will eat the grain.

How many trips will it take?__________________________

 

 

 

 

Mental Maths

 

For our mental maths focus, the pupils have been working hard on developing their times tables knowledge, particularly with the 3 and 4 times tables.

2D Shape Hunt

 

P5 have been revising the properties of 2D shapes, we spent time searching around the school to find all the examples of 2D shapes.

Subtraction

 

P5 have been working on our mental and written methods of subtraction. We used our outdoor classroom to partition our numbers into Hundreds, Tens and Units to help with our subtraction methods.

 

Telling the time

 

P5 have been working on reading the analogue clock to 15 minute and 5 minute intervals using various methods of activity based learning, ipads and worksheets alongside making their own clocks.

Venn and Carroll diagrams


We have been looking at Venn and Carroll diagrams as a way to classify Rainforest animals during our outdoor learning this week. We considered whether the animals are mammals, birds, fish, amphibians or reptiles. We also used the diagrams to sort which layer of the rainforest these animals live in.
The rainforest layers are:

  • forest floor
  • understorey
  • canopy
  • emergent

Ordering and comparing numbers

 

We were finding different 2, 3 and 4 digit numbers outside like a treasure hunt. We then spent time in our outdoor classroom comparing and putting these numbers into ascending order.

Place Value

 

P5 have been revising place value of numbers up to 10,000 using various practical materials.
