2 The Learning focus of Practice 18 is Counting and Sequences 1,&2, Number Patterns 1&2, Multiply by 10,100,1000 and General Maths 1 Page 2 Counting and Sequences 1 What is a Sequence? A Sequence is a list of things (usually numbers) that are in order. Question 1 Put the numbers in order of size smallest to largest, for example: Practice ordering these numbers smallest to largest. 745, 34, 121, 564, 99, 17 Question 2 a) Put the numbers in the correct order. The number line is between 0-1000. Remember it is always helpful to find the halfway mark first. (500) b) Put the numbers in the correct order using a number line between 500 and 600. When trying to locate the value of each increment, in this instance, the difference between 500 and 600 equals 100. There are 10 increments, therefore 100÷10=10. Each value of the increment is 10. Question 3 Using the 4-digit cards, make the largest number and smallest number you can. Question c) make a 3- digit number larger than 750. Practice: Only using the digits 9, 3, 7, 5 make the largest and smallest 3-digit number.
3 Page 3 Counting and Sequences 2 To find a missing number in a Sequence, first we must have a Rule Sometimes it helps to find the differences between each pair of numbers ... this can often reveal an underlying pattern. Question 1 Find the missing integer (a whole number) by locating the rule to the pattern. Sometimes to find the rule we can find the difference in between the numbers to locate the repeating number pattern. Using a number line can also help us to solve the question. Questions 1c and 1d are decimal numbers. Remember, decimal numbers have a whole number part and a fractional part separated by a decimal point.
