Subtraction
Math Facts Stamps
Designed to meet these objectives:
Math
• Students will develop proficiency with
subtraction facts.
• Students will demonstrate understanding and use
of standard subtraction algorithms.
Reinforce math facts with these fun subtraction fact
stamps. The foam stamps are easy to use and great
for quickly practicing groups of facts. Use them to
create math facts books, fun facts tests, and games—
or place them at a math center for independent
practice. The possibilities are endless!

What’s Included
• 12 foam stamps
Getting Started
Set out stamps, stamp pads, and plenty of paper.
Using Your Stamps
Whole-Class Activities
• Create a reproducible for each student using the
stamp you wish to practice. Give students a
time limit and have them try to complete the
subtraction sentences as quickly as possible. Check
their work as a class.
• Have students create math facts journals. Have
them start with “-1” and move on to the next set
when ready. Have students practice with the stamps
each day.
Small-Group Activities
• Play Subtraction Bingo! Divide students into small
groups. Use four of the stamps to make a different
bingo sheet for each group. (Stamp the equation
sets side by side in one row. Use different stamps
on each sheet.) Make master copies for yourself
with all of the answers. Have each group work
together to complete the subtraction sentences on
their bingo sheet. When the groups have finished,
call out various answers. If a group finds the answer
2
on their sheet, they circle it. The first group to have
four answers in a row horizontally, vertically or
diagonally wins.
• Place the stamps in a math center for students to
practice with. Have students track their progress by
placing stickers on a subtraction facts poster to show
the facts they have mastered.
Meeting Individual Needs
ELL
• Pair students of different English language abilities
together. Have them stamp a set of subtraction
facts. Allow them to discuss the answers together.
• Have students stamp the subtraction facts you want
them to practice. Complete the equations together.
Then, have students create an index card for each
fact. Have them draw a picture to illustrate the fact.
For example, to represent “11 - 2 = 9,” they could
draw 11 items and cross out 2. Punch a hole in the
top left corner of each card and put them on a ring.
Students can keep them at their desks as a
reference tool or take them home for extra practice.
Reteach/Extra Support
• Work with a small group. Provide students with
counters they can use to help them find the answer,
3
or encourage them to draw illustrations to help
them solve the problems.
• After stamping the equations, cut the paper in half,
so that students only have to solve 5 of the
problems. When students have solved the first 5, let
them do the equations on the other half of the
paper.
• Introduce students to fact families. Discuss which
number sentences belong to the same fact family.
Have students create index cards with one fact per
card. Have them group the fact families together
and complete each fact family by writing the
corresponding addition fact sentences on each card.
Challenge
• Have students choose two stamps and stamp them
onto a blank piece of paper. Ask them to fill in all of
the answers for the subtraction sentences shown.
Then, have students create their own practice
activity by writing the subtraction equations with a
missing number. For example, they might write
“10 = 6” or “
- 7 = 3.” Have students write
a set of equations for the math fact they are
practicing, and then trade with another student.
Encourage them to time themselves to see how fast
they can complete the equations.
• Students can also practice other facts, such as
“-11,” “-12,” etc.
