Data and Graphs (Day 1)

Teachers collect, organize, and
represent data using frequency, bar,
and circle graphs. They use line
graphs to describe change over time,
and use benchmark fractions and
percents and the three measures of
central tendency—mode, median,
and mean—to describe sets
of data.

Algebraic Thinking (Day 2)

Teachers use a variety of
representational tools—diagrams,
words, tables, graphs, and
equations—to understand linear
patterns and functions. They connect
the rate of change with the slope
of a line and compare linear with
nonlinear relationships. They also
gain facility with and comprehension
of basic algebraic notation.

Number and Operation Sense (Day 1)

Teachers are introduced to
research on how students develop
facility with rational numbers
and to develop visual models
for operations with fractions,
decimals, and percents.

Proportional Reasoning (Day 2)

Teachers use various tools—objects,
diagrams, tables, graphs, and
equations—to understand
proportional and nonproportional
relationships and learn which
tools are most useful in particular
situations. Participants have
opportunities to explore situations
when direct proportion is
applicable and those when it is not.
