1 Date: 30/11/2014 WALT: Divide a two digit number by a single digit number using short division.

2 What is a 2-Digit Number? Any number from (and including) 10 to 99 For example: 54 87 12 75 94 43

3 2-Digit numbers are: 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99

4 What is the same about all 2-Digit numbers? Yes! They all have ONE 10 and a unit

5 Can you15 by 3? 15 3 = ?3.. 6.. 9.. Yes it’s 5! 24 4 = ?4.. 8.. 12.. Yes it’s 6!

6 If you know your tables.. You can divide!

7 How about 16 4? How many 4s in 16? Count in 4s Until you reach 16 4.. 8.. 12.. 16 16 4 = 4

8 How about 21 3 =? How many 3s in 21? 3.. 6.. 9.. 12.. 15.. 18.. 21.. = 7 Same as 7 x 3 = 21 You have turned into x

9 Well Done ! Now you are ready to divide a 2-Digit number. Try these and …… Good Luck!

10 Find the answers: 24 3 = 18 2 = 30 5 = 16 8 = 50 10 = 27 9 = Can you check your answer? 44 11 = Use the inverse operation.

11 Dividing is fun!

24 Date: 3/12/2014 WALT: Represent, extract and interpret data in tables, chart, graphs and diagrams.

25  What is data?  How do we go about collecting data?  Can you name the different means of interpreting data?  How do we collect data? DATA HANDLING

26 Classroom activities: SURVEY What is your shoe size? We will represent the data using a tally chart. FrequencyTallyShoe size

27 Classroom activities: Represent the data using a bar graph.

28 Date: 4/12/2014 WALT: Find the mode, median, mean and range of a set of data.

29 Mode: The mode of a data is the most common occurring number. Range: The range of a data set is the difference between the largest number and the smallest number Median A type of average, the middle value in a set of values ordered from least to greatest. Mean A type of average, calculated by finding the total of all the values in the set of data and dividing by the number of values. DATA HANDLING
