Plan: Plan for Year 1 Weekly Plan: Week 5 Block C1.a: Compare two or more lengths or heights by direct comparison Block C1.b: Measure lengths using uniform non-standard units Day 1 2 3 4 Mental oral starter Know the number pairs to 6. Divide class into 2 teams. Give each team a dice and a name. Child from team A throws their dice. Chn identify the number and one of them writes it on flip chart. If team B’s throw adds to this number to make 6, they score a point. Objectives [Y1] Compare two or more lengths or heights by direct comparison Count on or back in 1s from different numbers. Give each child a large number card between 0 and about 30. Start with the largest number. The child holding that card says his number. The child with the next number countingback says her number. Continue like this. Say a number 1 more than any number up to 30. Divide class into 4 teams; divide each team into pairs and give each pair a number card. Each pair must work out the next number and say it to each other. Choose 2 pairs in each team, if they get it right, their team gets a point. Estimate a number of objects up to 30. Tell chn that different things will be put in the straw hat and they have to guess how many. Child takes several double handfuls of loose beads. Place these in hat. Chn estimate on whiteboards. Check by counting, grouping in10s as you count. Main teaching Hold up 2 scarves. Which is longer?We can find out by placing them side by side. Chn stretch out 1st scarf on floor; the 2nd is placed beside it, ends lined up. Which is the shorter? Extend to comparing 3 scarves. Use the vocabulary longer, longer than, shorter and shorter than.[ITR C1.a] * [Y1] C1.a.1 Seat chn in circle. Stand a selection of objects in the centre of the circle. [Y1] 1.1 p24 We are going to compare their heights. The height is how far the top of the object is above the ground. Select 2 objects. Place them side by side so it is easy to compare. Rpt for other pairs of objects. Make comparison statements. [Y1] Estimate then measure lengths, recording estimates [Y1] Measure lengths using uniform nonstandard units (whole, half and quarter) Hold up 2 objects: Which is longer? Compare them by placing them side [Y1] C1.b.1 by side. Hold up a drinking straw. We are going to place the pole on the floor and see how many straws placed end to end, will match its length. Compare the result with the chn’s estimates. Rpt to measure the length of 1 or 2 more objects using the straws. Hold up 2 objects. Which is taller? Place them together standing on the floor. Hold up a pencil. We are going [Y1] 1.1 p25 to find how many of these match the height of the object. Invite chn to guess. Lay the object on its side and lay the pencils end to end. Chn count the pencils together. Rpt to measure the height of a chair.

Choose another object. Compare one of the chn’s objects with yours. Is this longer or shorter? Test it. Rpt for other objects. Compare lengths using direct comparison. Use language associated with measuring length. Compare the heights of pairs of chn when they are standing apart and then when they stand back to back. Extend to comparing 3 chn. Compare the heights of individual chn with objects in the classroom. Compare height using direct comparison. Use language associated with measuring height. Play ‘Guess the length’. Choose a length, choose a unit, for example straws. Children each write an estimate of the object’s length in the unit given. Whose estimate is closest? Measure and estimate length/height using uniform nonstandard units eg straws. Measure the height Estimate, measure of a child using both and compare pencils and gluelengths using sticks. The child lies uniform nonflat on the floor while standard units. other chn lay the units carefully alongside. Day 5 Mental oral starter Add two small numbers with totals below 10. Team A has 2, 4, 6, 8, 10. Team B has 1, 3, 5, 7, 9. Child from each team stands at front, with a hand behind their back. On count of 3, both bring out hand with fingers standing and some folded down. Add numbers. The team with that total gets a point. Objectives Main teaching * Choose child to lay out 5 pens end to end. We are looking for objects that [Y1] C1.b.3 are longer than 5 pens. Chn make suggestions. Test out objects. Stress need to line them up end to end. Rpt for other objects that are more than 5 pens long or less than 5 pens long. ** [Y1] 1.1 p26 © Pearson Education Ltd 2009 *** [Y1] 19 **** [Y1] Ch.p11 Plenary Choose a length e.g. 6 pegs. In pairs chn find an object that they estimate to be 6 pegs long. Test them by laying them alongside 6 pegs placed end to end. Whose objects are close? Outcomes Estimate, measure and compare lengths using uniform nonstandard units. Use language of measuring.
