As I tutor children with learning disabilities, I find that the same concept must be approached many different ways. The flashcards are another example of what I have done to help students to understand place value.
This is a set of numbers 0-9 for each place ones, tens, hundreds. The words ones, tens, and hundreds are below each number. Each place ones, tens, and hundreds is another color. I made additional sets for variety. The first set is with bright colored backgrounds and the numbers in contrasting light colors. The second set is with pastel colored backgrounds and the numbers in black. The third set is white backgrounds with numbers in black. The fourth set is white backgrounds with numbers in bright colors.
This teaching aid is free for you to download. I hope that it can be an assistance to you. Please leave reviews and follow me as I continue adding more to my store on Teachers Pay Teachers.
