• 1. <ul><li>TEACHINGWEEKPMV YEAR 7 – FUNCTIONAL MATHEMATICSTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKS2 hours1. NumbersRead and write and represent numbers up to 10 millions.Review reading and writing numbers up to and greater than a million:Five million, three hundred and fifty four thousand and twenty-five.Write in words: 9 234 207.Write a whole number as an expanded numeral using powers of 10.e.g. 234 567 = 200 000 + 30 000 + 4 000 + 500 + 60 + 7Rewrite using number words or numerals5 000 000five million400 000four hundred thousand30 000thirty thousand 2 000two thousand 600six hundred50fifty7sevenExample: Read 5 432 657Putting the words together, we have“Five million four hundred and thirty-two thousand six hundred and fifty-seven”TEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKS4 hoursDemonstrate concretely and pictorially an understanding of place value to millions.6000400 30 76000400307 6437 Read each of these numbers individually and then combine them to form the required number. Guide pupils to read this number as: “Six thousand four hundred and thirty-seven”.Number cards512037Use these digits to form- the greatest possible number,-the least possible number,- five other possible numbers,- write these numbers in words,- arrange the numbers you have formed from the least to the greatest.The police department is counting the number of cars on a certain road. The counting meter now reads47399What will it read after one more car passes by?Flash cardsTEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKS2 hoursYou are given the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 Put one digit in each box so that the answer will be as large as possible. 4 231 = (a digit can be used only once).Put one digit in each box so that the answer will be as small as possible. (a digit can 431 2 = be used only once).1.3 Compare numbersGuide students to arrange numbers in order of size. Use a place-value board if necessary to help pupils understand the process of comparing numbers.Activities on compare numbersPlace value boardFlash cards
• 2. TEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKS3 hours3 hoursRound off numbers to the nearest, 10, 100 and 1000.Explain the importance of rounding off in everyday life.Review the meaning of the word “nearest”. Review rounding of whole numbers less than 100 to the nearest 10.Round numbers to the nearest 100. Use an appropriate number line.Example: 236 is nearer to 200 than 300. Therefore, 236 is rounded off as 200, to the nearest hundred.Discuss the case of 250 being round off as 300 by convention (as in the case of 25 being rounded off as 30).Round off 5-digit numbers and discuss the rounding of mid-way numbers such as 3500 is rounded off as 4000 (to the nearest 1000).Number line strip.Addition and subtraction of numbers up to 10 000.Add and subtract numbers up to two 3-digit numbers without using calculators.Use calculators for adding and subtracting 4-digit numbers.Estimate and add or subtract.287 + 156 (first estimate by rounding)= 300 + 160. Therefore the sum should be around 460.1092 - 363, (first estimate by rounding)= 1100 – 400. Therefore the difference should be around 700.Solve word problems.Check reasonableness of answers.TEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKS5 hours2 hoursMultiply and divide numbers up to 10 000 either by computation or by using a calculator.Review the basic facts of multiplication and division.

Relate the concrete multiplication to the symbolic form.Multiply a 3-digit number by a 1-digit number.Example: 4 314Estimate answers in calculations.Check reasonableness of answers.TEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKS2 hoursGuide pupils to estimate the product before multiplying. 314 is about 300. The product of 300 and 4 is 1200.The actual answer should be around 1200. 314 = 300 + 10 + 4 4 314 = 4 ( 300 + 10 + 4) = 1200 + 40 + 16 = 1256Use a similar approach to multiply a 4-digit number by a 1-digit number.Consolidate the vertical format of multiplicationMultiply a 4-digit number by 10.Discuss multiplication of 1-digit, 2-digit and 3-digit numbers by 10 before proceeding to 4-digit numbers.Examples:4 x 10 = 4035 x 10 = 350572 x 10 = 57204519 x 10 = 45190TEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKS3 hours1.8Divide numbers up to 4-digit by 1-digit (without remainder).Review division algorithm involving 2 and 3 digit numbers and 1-digit divisors. Use concrete materials and drawing techniques before moving on to symbolic techniques. Establish the symbolic representation by using concrete materials.27813029210Use a similar approach for 4-digit divided by 1-digit.Estimate answers in calculations.Check reasonableness of answers.Solve word problems involving division.

Use parts of a fraction circle as shown below. Guide pupils to name the fractions represented by it. 9 pieces of is = + + = 2Lead pupils to see that an improper fraction is a number equal to or greater than 1 that is an improper fraction can be written as a whole number or a mixed number.Guide pupils to do this by computation.TEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKS3 hoursAdd and subtract simple fractions concretely, pictorially and symbolically.Add and subtract like fractions.The pupils have learned the concept of fractions and renaming fractions in their equivalent form. At this stage of learning fractions pupils would be familiar with adding and subtracting like fraction For example: + = 1 eighth3 eighths4 eighths orSubtraction of like fraction = Add and subtract of related fractions.In the case of related fractions, the fractions are first changed into like fractions before addition or subtraction.Example: + = + = When addition of fractions gives an improper fraction then the answer is written as a mixed number.

TEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKSsGuide pupils to understand that the numbers to the right of the dot (or point) represent the fractional part.1 hour3.2 Read, write and interpret decimals up to 2 decimal places.Another way of looking at ones and tenths are as follows:699770221615Provide pupils ample practice on writing decimals based on diagrams and decimal grids.2 hoursState the value of the digits in the tenth place and the hundredth place. Twenty seven hundredths is written as: 0.27 TEACHINGWEEKTOPICS AND OUTCOMESINSTRUCTIONAL APPROACHES AND STRATEGIESRESOURCESREMARKSKnow what each digit represents. Partition numbers into tenths and hundredths.Example: In the number 3.27, the digit 3 represents 3 ones, the digit 2 represents 2 tenths and the digit 7 represents 7 hundredths. Or 3.27 = 3 + 2 tenths + 7 hundredths or 3.27 = 3 + + Use the place-value mat for this purpose.Explain that 0.3 and 0.30 as representing the same value and that 3 tenths equal 30 hundredths. 2 hours3.4 Compare and order decimal numbers up to 2 decimal places.Use the models or the decimal grids to help pupils compare two decimal numbers up to 1- and 2-decimal places.
