Let us Do at Home — Page 25Seeds, and the stone path
Activity
Q1Fill a small container like a small bowl with seeds such as kidney beans, chickpeas, etc. Look closely at the container to estimate how many seeds are in it. Your Estimate: ……… seeds. Now count and see how close your estimation is to the actual number of seeds. Counted ……… seeds. Guess how many times you need to fill the container to get close to 200 seeds? Your guess: ……… times.
Answer
(write your own numbers):
My estimate: about 40 seeds.
I counted: 50 seeds.
50 + 50 + 50 + 50 = 200. So I fill the bowl about 4 times.
Q2Write the numbers in order on the stones.The path of stones. Only a few stones carry a number.
