Transcript Numeracy & Literature Powerpoint Presentation

Developing Numeracy
Through Literature
Why use children’s books?
• Children love books
• They love the stories and the illustrations
• Books present many mathematical
situations in a story context
• Non-fiction books present information to
help children make sense of their world
• “Books extend and develop children’s
ideas of the world, but at the same time
these ideas are bounded by the confines
and constraints of the story…this can help
the children focus on the mathematical
ideas within the text.” (Griffiths and Clyne,
1988, p 5)
• “Literature goes beyond the story setting
and provides a context which is interesting
and meaningful to children, as well as
presenting them with investigations which
interest and excite them.” (Griffiths and
Clyne, 1988, p 4)
• Mathematics should not be imposed upon
a work of literature….rather, the
mathematics should flow from it, and be a
natural part of the book.
• Children’s natural love of books should
never be put at risk by imposing “activities”
on them.
The purposes of the session are to:
• Introduce a number of books you may not
have seen before
• View some student work samples
• Investigate some mathematics questions
that have come across as a result of
reading these books to children
• Increase our own mathematical knowledge
In the EYNRP (Dept of Ed, Vic) only
• 10.9% of reception children recognised
all triangles
• 23.8% of Yr 1’s
• 35.3% of Yr 2’s
• 47.4% of Yr 3’s
• 59.2% of Yr 4’s
TASK
• Make a set of polygons showing how the
triangle changed from having three sides
and three angles to having many sides
and many angles.
RULE:
• Each corner of the every polygon must
touch the circumference of the circle.
USING THE POLYGONS TO
INVESTIGATE:
• Names (and the patterns in naming polygons)
• Uses of polygons in daily life
• Properties of polygons including:
–
–
–
–
–
–
–
Regular and irregular
Number of Sides and Angles
Symmetry
Diagonals
Tessellations
Triangles
Quadrilaterals
Use the sets of polygons to measure
–Length of each side
–Perimeter
• Discussing methods
• Finding and describing
generalisations
• Developing formula
Measuring Area
• Discussing methods
• Finding and describing
generalisations
• Developing formula
QUESTION: In what ways can a
triangle help in determining the area
of regular polygons? – record this as a
rule (formula)
Measuring Angles
• each angle
• sum of each interior angle
QUESTION:
• What is the rule for finding the sum of
interior angles for any polygon?
