Number-Family Teaching Methods™
amazing Number-Stick™ (Fun-Abacus™)
THE NUMBER FAMILY IDEA
understood from an example. Here several random 'strikes' have been made with
a 3-ball Number Stick.
They show various members of 'Number Family 3 and children
will read them as '2 and 1' (or '2 + 1 = 3), and so on..
all the members of a family can soon be learned
through a variety of games and activities. It is ‘part-whole’
learning and will
have huge benefits for children as they
proceed in mathematics.
A KNOWLEDGE DATABASE
of inter-related number relationships (bonds) to 10 and then to
systematically getting to know each number family.
They will be able to move around in it mentally, creatively. It
will last them all their lives.
The Number Stick
Fun Abacus™ is an extraordinarily versatile maths exploration
tool and toy. Use it from
K to 3 in different modes for
different purposes: The graphic to the right shows the '4 and 2'
member of Number Family 6.
enables children to create, describe and work with patterns
based on colour and space.
provides a dice of any size from 1 to 20. Dice sizes of 3, 4
and 5 are particularly useful in earliest early numeracy as
regards counting and number recognition.
Dice sizes from 10 to 20 can be useful in Grades 2 and 3.
Visual Number Line Mode
line of up to 10 balls which act like digital switches,
‘off’’ when down and ‘on’ when up.
The line extends to 20 or beyond by joining sticks and has
Slavonic abacus features which help identify number
in relation to 5, 10, 15, 20…
The pictured number line shows ‘3’. It is clear that it will
take 7 more (5 and 2) to make 10.
Number Family Mode
allows manual or random generation of Number Family
patterns such that, for example, manipulation of a 5-ball
Number Stick provides patterns of all
members of Number Family 5 such as ‘1 and 4’, ‘3 and 2’, and
‘0 and 4’. Its use in a variety of games and activities can
quickly and enjoyably lead to Number Family knowledge,
the comparison of numbers.
Alternating Pattern Mode
facilitates the understanding of multiplication and
division. A graphic clearly shows
'how many 2s in 10?' and 'how many 3s in 10?'
provides a new way of learning basic multiplication facts.
It is a peripheral Number Stick use
but may have useful
possibilities come to mind when, for example, red, yellow
and blue ten-ball sticks are joined together
to make a
simple computing device, where red balls are
hundreds, yellows are tens, and blues are ones.

extends mainly from K-2.
The Early Numeracy Pack suits year 1 and 2 of primary school.
There is also a Pre-School or Kindergarten pack.
It may be noted that the Number Stick may be used as an aid in
MOST of the activities K-2 in the United States Core Curriculum.
