kilometre and hectometre: 1 kilometre (km) is equal to 10 hectometres (hm). In other words, 1 km = 10 hm. litre (L) and centilitre (cL) 1 litre (L) is equal to 100 centilitres (cL). In other words, 1 L = 100 cL. litre (L) and decalitre (daL) 1 decalitre (daL) is equal to 10 litres (L). In other words, 1 daL = 10 L. kilogram (kg) and decagram (dag) 1 kilogram (kg) is equal to 100 decagrams (dag). In other words, 1 kg = 100 dag. kilogram (kg) and milligram (mg) 1 kilogram (kg) is equal to 1,000,000 milligrams (mg). In other words, 1 kg = 1,000,000 mg. gram (g) and milligram (mg) 1 gram (g) is equal to 1,000 milligrams (mg). In other words, 1 g = 1,000 mg.

Activity 1 • Provide a couple of questions or provide worksheet 1 to allow learners to apply the concept to convert one unit to another (metre, litre and gram). • Ask learners to exchange their worksheet with their peers and Provide following links to let learners correct their peer’s work. https://www.unitconverters.net/length-converter.html (length convertor) https://www.unitconverters.net/weight-and-mass-converter.html Mass and weight convertor https://www.unitconverters.net/volume-converter.html capacity convertor Worksheet 1: https://drive.google.com/file/d/1zbRxVtXPur7jD5KlE_ytVoKQPyoNYSu0/view?usp=share_link Activity 2: • Provide simple word problems related to linear SI units. Or share the worksheet 2 and let learners solve the problem. https://www.liveworksheets.com/vx3298247cb • Once they are done, discuss the solution through a whole class discussion.
