Thanks to Carolyn Markel from Jane Addams Resource Corporation for sharing this fun and easy math idea! Carolyn is part of the northern Special Learning Needs Institute group.
For teaching fractions, decimals and percents, I write different
fractions, decimals and percents on index cards (maybe 30 or 40). I
shuffle the deck of cards, and I have my students gather around a large
table. I tell the students that one end of the table is "0" and the
other end is "1". Each student takes turns selecting one of the index
cards. The student has to place his/her card at the appropriate spot on
the table. For example, if one student selects 1/10, the student would
put the card towards the "0" end of the table. If the next student
selects 55%, the student would put that card between the 1/10 card and
the "1" end of the table. It gets harder and harder as more students
put more cards down on the table because the students have more
choices as to which two cards their card should be placed between. At
the end of the activity, the whole table is full of
fractions/decimals/percents in order from least to greatest - it sort of
creates a giant number line. The students find it helpful to see how
the values of different numbers are related to one another. As a
teacher, I learn a lot about my students because I get to watch their
decision-making process in action, and correct misunderstandings
immediately.
