YR Maths activities for week commencing 6th July
This week we are continuing the theme of measures but looking at weight. Your child may already have some experience of weight through carrying heavy and light items. Encourage them to make direct comparisons using their hands to estimate which item feels the heaviest and then use a balance scale to check. Prompt them to use the language of heavy, heavier, heaviest, light, lighter and lightest to make comparisons. Avoid the common misconception that bigger items are always heavier by providing some small, heavier items and some large, lighter ones. They will then move on to using the balance scales to make indirect comparisons by measuring how many cubes or beads balance each item.
Monday 6th July Provide your child with a selection of items. Ask them to hold each item in their hand and sort them into a group of heavy items and a group of light items. Encourage them to compare items, using the sentence ‘the ______ is lighter than the ______’ or ‘the ______ is heavier than the _______’. Ask your child if they have any idea how they can check to see if they are correct. Explain that we can use a balance. This is a bit like a sea-saw and the heaviest object will go down. Make your own balance scales using a coat hanger, some string and 2 plastic tubs. See the link below. https://www.wikihow.com/Make-a-Balance-Scale-for-Kids Once the scales are made wath the following video https://www.youtube.com/watch?v=ybEU-6U7s8k to explain how the balance works. Allow your child time to play and investigate, encouraging use of correct language to make comparisons.
Tuesday 7th July
Give your child an object such as an apple. Explain that today they are going to go on a hunt! They will need to have a look around the house and find 3 things that are heavier than the apple and three things that are lighter than the apple. They must find these items just by holding them, the apple in one hand, the other object in the other hand, to feel the weight comparison. Once they have selected their items they should then use their balance to see if their predictions were correct. Can they record what they found pictorially?
Complete the following sentences;
• The _____ is heavier than the apple.
• The _____ is lighter than the apple.
Extension: Can they work out which item from the 7 is the heaviest and which is the lightest?
Wednesday 8th July
Set up a role-play Post Office. Wrap up a few parcels of different sizes and weights. Ensure that you have a small parcel that is heavy and a large parcel that is light so that you can dismiss the common misconception that all big things are heavy and all small things are light. Begin by asking your child just to look at the parcels and tell you which they think will be the heaviest and lightest by sight. Order them for your child and talk through their order. “So you think that this parcel is the heaviest and this one is the lightest. You thought that this parcel would be heavier than this parcel”….etc. Now let your child hold each parcel. Ask them to tell you what they notice and to rearrange the parcels accordingly. How many parcels can they correctly order by weight?
Thursday 9th July https://www.youtube.com/watch?v=ZpFWuHSDFtQ Watch the story ‘Who sank the boat’ by Pamela Allen. Give your child two different selections of resources from which to make two boats. For example, a paper boat and a Lego boat. Which boat do they think will carry the most weight and why? Encourage them to investigate which boat when placed on water can hold the heaviest cargo.
Friday 10th July
Recap with your child what happens to the balance scale when an item is heavier (it goes down) or when it is lighter (it goes up). Explain that today we want to find out how much something weighs. What do they think will happen to the balance scale when the things in either side weigh the same? (they will balance/be level). Ask your child to choose 3 items to weigh and provide them with cubes, all of which need to be the same size to provide a non-standard unit of measurement with which to balance each item. Help them to find the weight of the first item by making the scale balance with the bricks. Count how many bricks the item weighs and record it on a piece of paper. Allow your child to weigh the next two items as independently as possible, only helping if needed, and record their findings. Which item was the heaviest? Which item was the lightest? Can they order the three objects by weight?
Don’t forget that baking activities will also help your child to understand the concept of weighing and measures!
Please continue to play ‘Numbots’ and ‘Maths Factor’.
