for Flag Day
students will explore the number 50.
- Groups of 50 items for
each pair or small group of students. (Use items
such as counting bears, unifix cubes, pennies,
toothpicks, beans, etc.) If working as a whole
class, only one group of items will be needed.
- Discuss the number
50. Relate it to the U.S. flag and how there are
50 stars, one for each state.
- Put the students in pairs
or small groups. (With younger students, this
lesson may want to be done as a whole class.)
Give each group of students their 50 items.
- Guide the students through
a session of grouping the items in different
amounts. For example, start with putting them in
piles of 10's. Practice counting by 10's.
Do the same for groups of 5's and 2's. Have two
of the groups combine their items and count them to
see what 50 + 50 =.
- Explore the number 13
(since there are 13 stripes on the flag).
- Have a lesson on
symmetry. Print out pictures of symmetrical
flags and ones that are not symmetrical. Use the
following link for assistance in finding pictures, National
Flags. Cut the pictures or fold them
in half to demonstrate symmetry. Are both halves
the same or are they different? Have the
students draw one of the symmetrical flags and one of
the asymmetrical flags for concept
reinforcement. Using the coloring printouts at
the following web site may be helpful Coloring
Book Of Flags. Drawing a dotted line down
the center of the flag, or folding it in half will
help with concept mastery.
- Have pictures of different
flags available for the students to view.
Explore how patterns are used in flags.
- Have a lesson on 1/2 by
discussing a flag flying at half mast.
- Have the students make
small flags out of straws (for the flag pole) and
pieces of rectangular construction paper. Once
their flags are complete, work as a whole class to
create patterns in how the flags are placed. For
example, a flag pointing to the left, a flag pointing
to the right, etc. Or one student holding a flag
over his head, another student holding a flag by his
waist, etc. Therefore, the students bodies and
flags are part of the pattern.
