Measurement - (Level 2-3)
Purposeful measurement -
Prepare maths/measurement lesson with a purpose so children can give purpose
and reason to their learning.
The idea is measurement but
the calculation is number.
Squares is measured in
squares.
Volume is measured in
cubes.
Length is measured in
lines.
Weight:
You cannot learn what
weight is with a scale, or just by looking at it.
You need to give them
weight to actually feel, give them the experience of weight so they know what
weight feels like.
Give
a student a rubber band and find the perimeter.
How
could you change the perimeter? (Stretch it)
Not
what they always are, we can make them what we want them to be.
Static Measurement
It just is, you do it.
Measuring the shortest
distance from A to B. (Straight line)
Dynamic Measurement
You have a chance to change
things around, not the same.
Investigating all the
options for the same thing.
Measuring the longest
distance from A to B. (Body make up - Wiggly line).
Area
We
need to get children working with squares when we are working with areas,
something like a 100s board. (Area is measured in squares not in straight
lines).
We
give a child a box using 6cm by 4cm, they say 24cm and it is wrong because we
measure squares in squares not cm.
-
Use squares to measure squares
-
At level 3 it should be written like 24sqm (square meters).
Time
We need to get children
understanding the relationship between analogue and digital time.
For example; it is seven thirty-five
(7:35) not twenty-five to eight (Language).
Use 5 times tables to tell
the time or use time for times tables. 7:35 is the same as 7 lots of 5. They
can relate that directly to a digital device which is what they will more
exposed to in this day and age.
3:40, it is 8 lots of
5.
Replacing 100 with 60.
Working with duration rather than time.
Reflection on Practice
After this PL, in my practice
I am going to work on making sure my lessons have purpose. This is with all
strands, not only measurement. I would like to make maths more meaningful so
that students can give purpose and reason to their learning, creating
experiences they enjoy and can always relate back to.
