Estimation game
Making an estimation isn't finding the exact answer but roughly finding the answer or judging a number or value by making a sensible guess.
For your activity today I would like you to estimate the amount of items of things you can find around your house. I will write a list of possible things for you to estimate but you can add your own or change them if you like.
In your books I would like you to draw a table like the one below
| Items | Estimation | Actual amount |
|---|---|---|
| Story books | ||
| Spoons | ||
| Teddy Bears | ||
| Shoes | ||
Fill in the table above by making an estimate of how many items you think there are just by looking.
Remember you are not counting them just yet.
Once you have written down your estimate you can count what the actual amount is.
How close was your estimate?
Have fun estimating
