Lesson Details

Key learning points

Within a mixed number, the whole number is the most significant part.
The whole number part of a mixed number can be used to decide which integers it will be placed between on a number line.
The fractional part of the mixed number can be used to establish exactly where it will be placed between these numbers.

Common misconception

Children may count the marks rather than the equal parts between integers thereby determining the unit that we are working with incorrectly.

Show that we need to count the equal parts in between the given integers, not the marks. You could model this with the same line with increasing parts.

Keywords

Mixed number - A mixed number is a whole number and a fraction combined.
Integer - An integer is a number that has no fractional part - they are whole numbers. This includes the counting numbers e.g, 1, 2, 3 and zero.
