This pack has flash cards for numbers 11-19 for students to decompose into 10s and 1s. Each number is on a different animal for easier differentiation between the numbers for our lower students.
I have students use unifix cubes to make a stack of 10 in the 10s place and then place individual cubes in the 1s place. Or they can use base 10 blocks. Once the card is laminated they can write the equation 10 + _____ = _________ at the bottom.
