Smarten up in Maths (age 8-9)Write in the missing fraction: 6 / 10 +……………….= 1---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------This is a “1” slab.•The “1” slab hasbeen divided into10 equal parts.Now write the fraction that is not shaded.Now the “1” slab hasbeen divided into100 equal parts.1•Its size is 1 unit.If we divide the slab into10 equal parts, each partis called 1 / 10 .If we divide the slab into100 equal parts, eachpart is called 1 / 100 .Colour the first threecolumns red.Write the fraction that isshaded Write the fraction that isnot shaded Write the missing fractions….…………….….. + ……………….. = 1DecimalsTenths & HundredthsDecimal & Fractional equivalenceColour the first threecolumns blue.Do you agree that30 / 100 of the slab is blue?Can you see that30 / 100 + 70 / 100 = 1 ?Can you see that30 / 100 = 3 / 10 ?Do you agree that1 / 10 = 10 / 100 ?If we divide $1 evenly between ten people each person will receive 10c.That’s because 1 / 10 of $1 is 10c.We may write the fraction 1 / 10 as a decimal number.1 / 10 is 0.1 in decimal language. So we can say that 0.1 of $1 is 10c.What happens if we divide $1 evenly between 100 people?This time each person will receive only 1c. (that’s if we had 1c pieces!)We say 1 / 100 of $1 is 1c. OR we could say 0.01 of $1 is 1c.© Intelligent Australia Productions23
