ESTIMATION 1
(Food)

• Hang several packets of sweets in a visible place in the classroom. In each bag there should be a different number of sweets. Use different coloured bags to more easily distinguish between them.
• In groups the pupils try to estimate the number of sweets in each bag (recording the numbers in the appropriate colour). “Can you guess how many sweets are in the green bag?”. “Write down the number using a green crayon, please.“ Help them if necessary by holding up a green crayon.
• Take the sweets down and give one bag to each table. With instructions not to open the bags “do NOT open” ask the children to feel the sweets and try to count them “Feel the sweets in the bag. How many are there?“ Again write down the number. Pass the sweets around so every group can touch every bag.
• Collect in all the sweets and then sit the children in a circle, or so everyone can see. Open each bag and count the sweets as a class. Write the numbers on the board so the children can verify if their guesses were accurate or inside an agreed level of accuracy i.e. + or – 5 sweets.
• Either use the sweets to reward the class or keep them and eat them yourself!

Extension Activity:

For more advanced students, the children count the differences in their estimations “How many more or less have you got?“ The pupils answer “I’ve got 4 more, 2 less…“ for example.
