Slide 2:
Picture: Connection Mathematics 7 Step1 : Always look at the scale first Each line equals 1mm. 10 small lines equals 1cm Write the measurement at point A and Point B Answer A= 3cm or 30mm Answer B= 6.2cm or 62mm
Slide 3:
Picture: Connection Mathematics 7 Remember : Always look at the scale first Write the measurement at point a and point b and point c Note: this reads 1m 700cm Note: this reads 1m 800cm Therefore b and c are in between 1m 700cm and 1m 800cm a = 1m 700cm b = 1m 720cm b = 1m 767cm In your workbook write the answers for a,b and c
Slide 4:
Picture: Connection Mathematics 7 When reading a ruler what must you always do first? Always look at the scale first Look at the ruler below and write in your workbook the measurements for A to H
Slide 5:
Picture: Connection Mathematics 7 Look at the ruler below and write in your workbook the measurements for A to H A = 8mm
0.8cm B = 20mm
2cm C = 45mm
4.5cm D = 72mm
7.2cm E = 72mm
7.2cm F = 107mm
10.7cm G = 111mm
11.2cm H = 134mm
13.4cm A = 8mm
0.8cm B = 20mm
2cm C = 45mm
4.5cm D = 72mm
7.2cm E = 72mm
7.2cm
Slide 6:
Picture: Connection Mathematics 7 Now it is your turn In your workbook, write the answers for a to f a=18cm b=19.5cm c=21.3cm d=23.7cm e=27.9cm f=29.2cm
Slide 7:
Picture: Connection Mathematics 7 Question: In your workbook write the values for a to f be between? 1. Does the measuring tape begin at zero? No 2. What measurements on the measuring tape are shown that helps work out the correct measurement? 2m 400cm and
2m 500cm f = 2m 505cm a = 2m 400cm b = 2m 430cm c = 2m 445cm d = 2m 467cm e = 2m 481cm
