Lesson details
Key learning points
- An understanding of the composition of the powers of 10 supports us when we solve problems.
- If we know one-quarter of 1,000 is 250, we know one-quarter of 1,000 thousands (1,000,000) is 250 thousands (250,000)
- Just as with smaller numbers, word problems can be represented visually as a bar model.
- A bar model supports us to form an equation to then solve.
Keywords
Million - One million is composed of 1,000 thousands. One million is written as a one followed by six zeros.
Common misconception
Children may misinterpret a word problem especially where they are insecure on the key words such as 'difference' or 'how much more'.
Teacher should model own thoughts when problem solving and encourage children to represent the word problems in a bar model. Construct bar models alongside a retelling of the problem so children can see where the mathematics is found.
