Year 1 Block D - Calculating, measuring and understanding shape Unit 1

Objectives

Children's learning outcomes are emphasised
Assessment for learning
  • Solve problems involving counting, adding, subtracting, doubling or halving in the context of numbers, measures or money, for example to 'pay' and 'give change'

    I can use counting to solve problems involving measures

How did you find out which of these two objects was the lighter, shorter, held the least amount, ...?

I am giving each of you six paper strips. Find two strips in your set which are the same length. Show them to me. Now find a strip in your set which is longer than this one.

What is each of these coins worth?

In how many different ways can you make 10p using only 2p and 1p coins?

  • Count reliably at least 20 objects, recognising that when rearranged the number of objects stays the same; estimate a number of objects that can be checked by counting

    I can find out how long a room is by counting the paces I take to cross it

Guess how many cubes are in the jar. Now check by counting. Why did you think it was that number of cubes?

How many cubes will balance the parcel on the scales?

How many glasses will fill the jug?

How many jumbo bricks do you need to make a tower that is as tall as you are?

  • Visualise and use everyday language to describe the position of objects and direction and distance when moving them, for example when placing or moving objects on a game board

    I can describe where something is using words like 'next to', 'in front of', 'underneath', 'on top of', ...
Who is sitting next to you?

Put the pencil pot in front of/behind the tray of crayons.

Stand in front of the board. Stand in front of, behind, beside, opposite a partner. Stand between two other children.

Show me your left hand.

Tell me something in the classroom that is higher than, lower than, above, below, between, beside, next to, in the middle of, at the edge of, in the corner of the ...

We can't see the hall, but what is next to the piano? What is below the big window?

  • Estimate, measure, weigh and compare objects, choosing and using suitable uniform non-standard or standard units and measuring instruments (e.g. a lever balance, metre stick or measuring jug)

    I can guess how many cubes will balance a parcel

    I can use a metre stick to measure how far it is across the hall

Where do you start to measure the length of the carpet?

Ann measured the height of these two dolls in blocks. How many blocks taller is the large doll?
Cubes against 2 Russian dolls

  • Use vocabulary related to time; order days of the week and months; read the time to the hour and half hour

    I know the days of the week and can say them in order

    I can remember the order of a favourite story

What day is it today? So what will tomorrow be?

Which are the weekend days?

Which days are we at school?

Look at these pictures. Point to a picture which shows something that you think happened in the morning.

Point to a picture which shows something that you think happened in the afternoon.

Point to a picture which shows something that you think happened in the evening.

  • Retell stories, ordering events using story language

    I can tell the robot step by step how to go around the chair and back to me

    I can tell the story of Goldilocks and the three bears

What happens first? And next?

What happens at the end of your story?

These cards tell a story of how some children built a snowman. Put the cards in order.

   

Learning overview

Children count, compare, add and subtract in contexts involving measures or money. This helps them to transfer their calculation skills from the context of number and apply them to the measures, and vice versa.

When they are working with money, children initially use only 1p coins or only £1 coins to 'pay' in the classroom shop, counting out coins for an object that they want to buy. They buy a number of 2p stamps using 2p coins. Slowly, they understand that a 2p coin has the same value as two 1p coins, and that a £2 coin has the same value as two £1 coins. They begin to read and write prices such as 8p or £4, responding to instructions such as:

Tell me how much you think this toy boat costs. Watch while I write how much it is.
This toy car costs 9 pence. Find a price label to match how much.

These activities can be demonstrated on an interactive whiteboard to a large group. They can also be linked to counting in twos to 10 and back again to zero, and to hops of 2 on a number line.

Children continue to make direct comparison of the length, weight or capacity of two objects without any counting. They begin to use uniform non-standard units to estimate and then measure length, using objects such as cubes or art-straws that are all the same size. They select an eggcup to measure the capacity of a small jug, and a larger jug to measure the capacity of a bucket, recognising that it would not be appropriate to measure the capacity of the bucket using the eggcup. They weigh on the scales parcels that have been carefully prepared by the teacher to match an equivalent number of identical bricks or weights, estimating first how many bricks will balance the parcel.

Children continue to develop the concept of time in terms of time passing and sequencing events in familiar story or day-to-day routines. They use terms such as morning, afternoon and evening, yesterday and tomorrow. They learn to order the days of the week and learn that weekend days are Saturday and Sunday. They listen to stories and rhymes about time, such as The Very Hungry Caterpillar or The Bad-Tempered Ladybird by Eric Carle, Monster Monday by Susanna Gretz or Hard Boiled Legs by Michael Rosen and Quentin Blake. They count how many times they can clap in a steady rhythm while a child writes their name on the board, and discuss who took more time and who took less time. They count regular beats on a drum while children pace across a room or cut out a square of paper. They estimate whether they can pack the bricks away while someone counts to 20.

Children use everyday language to describe position, direction or movement. For example, they place objects above, below, to the right of and to the left of other objects on a magnetic board or interactive whiteboard. They follow instructions to put play-people in a scene. In PE, they follow instructions to roll or slide, or to make whole and half turns on the spot. They turn to the left and they turn to the right.
