This is a resource that features 4 worksheets and a card-matching game with 4 levels for students to practice changing the expanded form of a number into standard form.
The worksheets all give the expanded form of a number in a mixed-up order. The levels include: basic expanded form, expanded notation, expanded form with decimals, and expanded form with fractions.
The card-matching game has the same 4 levels as the worksheets. Students will match up the mixed-up expanded form version of a number with the standard and word form of that same number. There are 12 cards for each form for a total of 36 cards per set.
This meets the CCSS standards:
4.NBT.2 and 5.NBT.3a
