A cut out and match activity where students must connect decimal numbers expressed in word form, standard form and expanded form. Students are challenged in this activity because each of the numbers has the same 4 digits! Students are further challenged to answer questions where they must compare the numbers to each other and order them from least to greatest.
This resource contains a set of 13 different numbers each expressed in standard form, word form and expanded form. Students receive cut-outs of the numbers expressed in different forms and they need to match them appropriately on a large chart according to standard form, expanded form and word form. Each of the numbers have the same 4 digits so students need to rely on their knowledge of place value in order to correctly match the numbers. Then, students need to reflect on their own thinking and compare the numbers to each other.
There are two versions of this sheet: one has a single cut-out sheet for each student (if you want students to cut out their own). The other version has class-set copies of each cut-out (e.g., an entire sheet of A’s) if you want to pre-cut the numbers for easy distribution.
The answer keys for the matching activity and for the questions are on the last two pages.
This resource can be used as a whole-class activity (individual or with partners), as an early-finisher task, or as part of stations. Debriefing student thinking after having students solve individually/with a partner is a great way to encourage sharing of ideas and to help struggling students hear the different ways to think about and match the different forms of numbers. Each answer expressed in standard form has a corresponding upper-case letter, each expanded form has a corresponding lower-case letter and each word form has a corresponding number, making it easy to discuss and check the matches as a whole group. The matching portion of the activity is aligned to 5.NBT.A.3.A, 5.NBT.A.3.B and the questions are aligned to 5.NBT.A.1 and 5.NBT.A.2.
This resource can also help students in older grades to read, write and compare
decimal numbers and to refresh their knowledge of the place value system.
