CHART TO BUILD NUMBER
SENSE
Presented by Paula Jones
AGENDA
Introduction to the hundreds chart – 15 minutes
Hundreds Chart Interactive Activity – 15 minutes
Connection to 8 mathematical practices – 10 minutes
Ten games using the hundreds chart – 1 hour
Wrap Up and resources – 20
OBJECTIVES
 Participants will gather resources and materials to incorporate
hundreds charts games into their EnVision math workshop.
 Participants will recognize how the hundreds chart can be used to
support the 8 mathematical practices.
 Participants will recognize the purpose of the hundreds chart is to
provide a framework for students to think about our base 10 system and
to allow students to build a mental model of the mathematical structure
of our number system.

 A 10-by-10 grid with the
numbers 1 to 100 printed in
the squares.
WHY USE A HUNDREDS CHART?
 Provide a framework for students to think about our base ten
system.
 Allows students to build a mental model of the mathematical
structure of our number system.
 Allows children to explore concepts from counting to adding twodigit numbers.
 Gives the opportunity to bring in several Mathematical Practices.
YOUR TURN!
 Take a moment to make a list of all the ways you currently use the
hundreds chart in your classroom.
 Turn and talk to a partner about what you currently do in your
classroom.
 Share out some of the ways we are currently using the hundreds
chart.

CHART
 Building a hundreds chart with your students.
 Arrow Arithmetic
 Where do these fit in with the 8 Mathematical Practices?
 What does the hundreds chart mean to kids conceptually?
 How does the hundreds chart connect to base 10 system and
number sense?
