Many educators and
mathematicians believe subitizing is an important readiness skill for later
math success. This means we should be aware of what this is and how to help
children and families.
Subitizing is the ability to
“instantly see how many.” In other words, children can immediately see how many
objects are in a set.
For more information on
subitizing, watch the video below.
You
can make subitizing tactile by using puffy balls or other 3 dimensional objects
that children can touch and manipulate in various arrangements. See our previous
blog post for more ideas http://www.maggiesbighome.com/2013/10/a-predictor-of-later-math-success.html
In
addition to the ability to visually tell how many objects are in a set, children
can also use auditory skills. Stomp, clap, or ring a bell and ask children to
tell you what they heard. Children can even draw dots or lines to represent the
number of stomps, etc.
We
also encourage you to use nature to provide subitizing opportunities. When
walking, point out groups of trees or flowers. Invite children to tell you “how
many.” Gather
children around and show them how to put fallen leaves in different
arrangements and then ask a friend to tell how many leaves they see. Visiting the pumpkin patch? Have children arrange pumpkins in different ways and ask others to tell how many are seen. Children
can arrange and rearrange them.
This is something you can encourage families to do at home. Soon, you
will notice that children are doing this on their own!
Why
not give families a definition of subitizing in your newsletter? Or better yet,
give them the link to this website!
