Understanding light reflection: Build your own periscope
Mirrors change the direction of light and reflect it. We can demonstrate this practically by making a periscope. Light is reflected from one object into a mirror and then onto the other mirror before reaching your eyes. Collect your materials and find out for yourself!
What is evaporation?
In this investigation you are going to see if water can move – or does it just change?
Food webs
When we look at habitats we often look at food chains to see the feeding relationships within them. Sometimes, though, more than one animal feeds off others. This is when we make food webs. Look at these cards. Can you cut them out and arrange them on the table with the arrows to show which animals feed off each other?
I hear with my little ear
Sit in a quiet place and close your eyes and listen really carefully. What can you hear inside the room? What can you hear inside yourself? Record the sounds you hear.
Using tally and bar charts
What’s your favourite part of Christmas? Find information about the best aspects of the festive season for as many people as you can by asking your friends at school and your family at home. They will need to choose from the list in the table. Keep a tally of the numbers using this tally chart. Now use these axes to draw your own bar chart to show the information you have found.
Subtracting three-digit numbers
When subtracting three-digit numbers, there are three different methods you can use. Work out these subtractions using whichever method you find easiest.
Solving two-step word problems
Can you solve these problems? Jot down the numbers you need to use on the notebooks. Think about the steps needed to work out these problems and jot numbers down as you go along. Ask a parent if you need help finding one half and one fifth of a number.
Mental maths checker: doubles and halves of two- and three-digit numbers
Can you double and halve these two- and three-digit numbers? Colour in a star every time you get 10/10!
Adding and subtracting multiples of 10, 100 and 1000
Try this quick mental maths checker – adding and subtracting multiples of 10, 100 and 1000. Colour in a star every time you get 10/10!
Perimeter investigation
How many four-sided shapes with a perimeter of 24cm can you create on the squared paper?
Perimeter explained
Imagine an ant crawling around the outside of a shape. The distance the ant walks is the shape’s perimeter. Perimeter is usually measured in centimetres and metres. Can you work out the answers to these perimeter questions?
Pairs of fractions that total one
Can you cut out these cards and match them up so that each pair of fractions total one?
Number sentences totalling 100 and 200
Look at these number sentences. What digits need to go in the gaps? Remember when adding two numbers totalling 100, the tens numbers have to add up to 90 and the units have to add up
to 10.
to 10.
Multiplying by 100
When you multiply a number by 100, use your place value skills to slide the digits two places to the left, then put two zeros in before the decimal point. Cut out these number cards. Each green number is an orange number multiplied by a hundred. Can you match them into their correct pairs?
Multiples of 5 investigation
Carol, Robert, Faye and Daniel all have collections of monster cards. Can you work out how many monster cards each person has from the information given?
Line symmetry
Something is symmetrical when both sides of it are the same when cut in half. The line down the middle of a symmetrical shape is called the line of symmetry or a mirror line. Can you draw the other half of each shape using reflectional symmetry? Use a mirror to check your work!
Length problems challenge
To help you with these length calculations, change metres into centimetres and trying drawing the answers.
Halving investigation
If you take any three-digit number ending in two zeros and keep halving it, you will eventually end up with a number that ends in 5. Do you think this is true? Test this out using this table to record your findings. Test every number possible.
Fractions of quantities
I have 16 bananas. I give ¾ of them away. How many have I given away? When working out fractions of amounts, divide the number by the fraction denominator (bottom number) then multiply it by the fraction numerator (top number). Can you use this method to work out the rest of these fractions?
Fractions and money
Her are some facts. Use them to help you work out these money problems. You'll need to use your fractions skills too.
Estimating and checking calculations
Susie has worked out answers to these calculations. Have a look through and estimate what you think the answer should be. Don’t spend ages working out the exact answer! Give Susie a tick if you think she is right or a cross if you think she is wrong. In the last column, explain why she is right or wrong. Afterwards, use a calculator to check whether Susie’s answers were right or not.
Doubling two-digit and three-digit numbers
When doubling a number, trying doubling each digit in turn and then adding them together. Use this method to double each of these numbers.
Dividing by 10
When you divide a number by 10, use your place value skills to slide the digits one place to the right. Can you divide each of these numbers by ten?
Describing direction
The line shows a journey taken by a ladybird. For each straight line, write down how many squares it has travelled and in what direction. The first three have been done for you.
