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.

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.

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.

Children need to understand, that with mixed numbers, the whole number part is the most significant part and tells us which two integers it sits between on a number line. Determining the unit we are working with is key to being successful so provide children with lots of practice at that.
