10. The pencil is 6cm long to the nearest cm. What mistake has Kat made? Explain your answer Kat has measured from 1cm instead of lining it up at 0. How long is the pencil? 5cm

11. Measure and order. tallest yellow blue pink shortest cm cm cm 10 12 11

12. Lesson 2 Step: Measure length (m)(Practical)

13. Fluency If we measured the size of the classroom, would we use a ruler? What could we use and why would this be better? Metre stick or tape measure

14. Fluency Outdoor activity: Measure how big you think one metre is with a piece of chalk. How close was your estimate?

15. Fluency Using a metre stick measure: Chair Can you name an item that is bigger? .. smaller?

16. Fluency Using a metre stick measure: Table Can you name an item that is bigger? .. smaller?

17. Fluency Using a metre stick measure: Door Can you name an item that is bigger? .. smaller?

18. Fluency What items could be measured using?.. Why would you use one over the other?

19. Fluency Sort the objects in the table below.

20. Sue is measuring around the stone which is more than 1m. What could I use to measure the stone as I am struggling with a metre stick? Sue could use a tape measure to measure around the stone.

21. Name three items that are shorter than one metre Name three items that are larger than one metre.

22. Lesson 3 Step: Compare lengths

23. Fluency Compare using longer than, shorter than or the same as. shorter than 6 cm is 16 cm longer than 1 m is 1 cm shorter than 67 cm is 76 cm

24. Fluency Compare using longer than, shorter than or the same as. longer than 22 cm is 20 cm the same as 1 m is 100 cm shorter than 34 m is 37 m

25. Fluency Compare using longer than, shorter than or the same as. shorter than Half of 12cm 7 cm the same as 29 cm 18 cm + 11 cm longer than 20 m – 3 m Half of 32 m

26. Fluency Compare using > , < or = < 13 cm is 31 cm > 96 m is 89 m < 47 cm is 50 cm

27. Fluency Compare using > , < or = > 31 cm is 13 cm > 7 m is 7 cm < 12 cm is 120 cm

28. Fluency Compare using > , < or = < 6 m + 18 m 27 m – 2 m = A quarter of 44 m 15 m – 4 m > 7 x 5 cm Half of 60 cm

29. Reasoning Four lots of 4 m > Quarter of 60 m False True  Explain how you know. Four lots of 4 m = 16 mQuarter of 60 m = 15 m 16 m > 15 m therefore four lots of 4m > quarter of 60 m.

30. Problem solving Complete the statements to make them true. < 9 m + 13 m = 7 x 12 cm > Third of 15 cm

31. Lesson 4 Step: Order lengths

32. Fluency Order the three tallest to shortest A B C D D B A C Tallest Shortest

33. Fluency Order the snakes shortest to longest. B A 8m 12m D C 6m 10m C B D A Longest Shortest

34. Fluency Measure then order the straws. Tallest red pink green yellow cm cm cm cm Shortest 7 5 6 9

35. Fluency Measure then order the straws. Tallest green blue orange purple cm cm cm cm Shortest 6 4 3 7

36. Fluency Order the following lengths shortest to longest. 21 m 19 m 9 m 11 m 9 m 11 m 19 m 21 m Longest Shortest

37. Fluency Order the following lengths shortest to longest. 1 m 65 cm 56 cm 11 cm 1 m 65 cm 56 cm 11 cm Longest Shortest

38. The length that should go in the box is 18 m. 6 x 3 m ? of 40 m Shortest Longest Is Sue correct? Explain your answer. No, Sue is not correct. The length would go in the box is 19 m.

39. Problem solving Use each digit card once to complete the boxes.Each length needs to be a 2-digit number. 6 8 1 4 9 3 Longest Shortest How many different ways can you think of?

40. Lesson 5 Step: Four operations with lengths

41. A balloon is 23 cm in length.The string is 32 cm in length. What is the total length of the balloon and string?Write a calculation to show this. + = 32 cm 55 cm 23 cm 55 The total length of the balloon and string is __________ cm.

42. Problem solving String A measures 17 cm long. String B measures 16 cm long. What is the combined length of both strings? Write a calculation to show this. + = 16 cm 33 cm 17 cm 33 The total length of string is __________ cm.

43. What is the total length of 9 sweets each measuring 3cm. Write a multiplication calculation to show this. = x 3 27 cm 9 cm 27 The total length of the 9 sweets is __________ cm.

44. Problem solving A length of rope measures 8m. 5m is cut off the rope.How much rope is left? Write a calculation to show this. - = 5 m 3 m 8 m 3 There is __________ m of rope left.

45. Problem solving Kat put 12 paper clips in a straight line. Each paper clip is 3 cm long. How long is the line? Write a calculation to show this. x = 12 36 cm 3 cm 36 The total length of the line is __________ cm.

46. Problem solving Ribbon A is 13 cm. Ribbon B is 10 cm. Ribbon C is 4 cm longer than Ribbon A. What is the total length of the three ribbons combined?Write a calculation to show this. 13 cm + 10 cm + 17 cm = 40 cm. Can you represent this on a bar model?.. Part-whole model?
