I am developing a sense of size and amount by observing, exploring, using and communicating with others about things in the world around me.
*Responsibility of all
|
I can share ideas with others to develop ways of estimating the answer to a calculation or problem, work out the actual answer, then check my solution by comparing it with the estimate.
*Responsibility of all
|
I can use my knowledge of rounding to routinely estimate the answer to a problem then, after calculating, decide if my answer is reasonable, sharing my solution with others.
*Responsibility of all
|
I can round a number using an appropriate degree of accuracy, having taken into account the context of the problem.
*Responsibility of all
|
Having investigated the practical impact of inaccuracy and error, I can use my knowledge of tolerance when choosing the required degree of accuracy to make real-life calculations.
