3-5
Students are familiar with sports and sporting events. Whole numbers
and fractions are used to represent the size of groups or collections
and measurements involving lengths, weights, and times in many sporting
and game situations. This knowledge can be used to give the students
another picture of numbers.
3-5
A post office is a good example of a real-world environment in which numbers of different types can be found. Whole numbers and fractions are introduced. Numbers that occur in a greater variety of measurement situations can also be introduced. At this level, students should be encouraged to elaborate on the way numbers are used.
3-5
Students participate in an activity in which they investigate the data
in connection with recyclable materials and develop plans to help the
environment. Students discuss the pros and cons of using various types
of bags at the grocery store. Classmates are surveyed to determine
which type of bag is the "best".
3-5
The teacher reflects on her own mathematical learning.
6-8
In this lesson, students complete a chart by multiplying or dividing a given value, compare two categories in a line graph, and identify number patterns.
3-5
Two video clips illustrate communication about mathematics among a teacher and her students.
Pre-K-2
Students use objects and symbols to make repeating linear patterns. They extend patterns and translate patterns from one modality (auditory, visual, and kinesthetic) to another. A Physical Education connection is suggested as an extension. This lesson is intended to take two class periods to ensure that all students have multiple opportunities to create original patterns.
3-5
Explore
relationships among fractions through work with the set model.
6-8
In this lesson, students develop a deep conceptual understanding between remainders and the decimal part of quotients. They learn how remainders and group size work together to influence the results that are displayed on a calculator. Students use beans to physically represent quotients that have remainders, and they compare remainders written as fractions of whole groups to the results obtained with a calculator.
