These fun cactus number-building cards are on point! Use this fun teaching resource in the classroom when exploring 3-digit place values.
Print, cut, and laminate the 3-digit number cacti cards and the hundreds, tens, and ones sombrero hats.
In small groups, students pick a card, say the number on the card, and 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.
Please note that multiple pages of the hundreds, tens, and ones sombreros page may need to be printed, cut, and laminated for larger group sizes.
