Students drag numerals to create decimal numbers to create the largest and smallest decimal numbers, and closest decimal numbers to given whole numbers.
Using information about the shape-based number system on planet Efilar, students display the base 10 numbers for Efilar shapes. Students also display Efilar shapes from given base 10 numbers.
This practical task requires students to order numbers with 2 decimal places from smallest to largest using digit cards. New numbers with 2 decimal places are then created with the digit cards.
