Learning intention: interpreting growth charts
Circumference reminds me of
Circumference of a circle
The boundary line
The distance around something
Perimeter of a circle
Percentile
Percentile is not the same as percentage
Rank
Can be confused with precent or percentage comparing something such as
test scores, height, salaries etc
Percentile charts are used to plot your baby's changing weight, length (or height), and head circumference, and are often referred to as 'percentile charts'.
Percentile charts aim:- to give you a visual indication about how your baby is
progressing over time.- See where they fall in relation to the rest of the population
average, for either girls or boys.
The percentile graphs are marked with curved lines that represent the different percentiles. The main percentile bands are the 10th, 50th and 90th percentiles, but they may also have the 5th, 25th, 75th and 95th percentiles.
Percentile ranks are an easy way to convey an individual's standing at graduation relative to other graduates.

If your head circumference lies on the 10th percentile, what does it mean?It means 10 % of the children have a circumference smaller than you and 90 % of children have a circumference bigger than you.
For head circumference
it means 25 of the kids have a circumference higher than you and 75% lower than you.
Q: If your head circumference lies on the75th percentile what does it mean?
If you lie on the middle which is the thick line (50th) you have the middle percentile (median) you are in the middle.
If your baby is on the 95th percentile, only 5% of other babies of the same age are heavier than your baby, and 95% weigh less.
For weight
If your baby is on the '10th percentile' for weight, it means that 90% of other babies their age are heavier than he or she is, and 10% of other babies weigh less.
Activity1Use a tape measure and measure your partner’s head circumference.Activity2Give students a blank chart and give all the words and they have to paste them on the graph.
Head Circumference ChartFor an accurate head measure, place a tape measure across the forehead and measure around the full circumference of the head.
