A fun place value activity for students to play in the classroom when exploring 3-digit numbers and expanded form.
Print, cut out, and laminate the 3-digit number cacti cards as well as the hundreds, tens, and ones sombrero hats.
In small groups, students pick a card, say the number on the card, then make the number by placing the corresponding number of hundreds, tens, and ones sombreros on top of the cactus.
Alternatively, provide the students with the blank cacti cards and have the students roll three different dice to determine the 3-digit number.
As an extension, encourage students to record and expand each number in their math journals.
Please note that multiple pages of the hundreds, tens, and ones sombreros page may need to be printed, cut out, and laminated for larger group sizes.
