Subitize and build number sense with these pattern cards up to 10! At least 2-3 different number patterns for numbers 2-10. Great for the sweet kinders and the firsties. I cannot brag on number talks enough and how powerful subtilizing cards are within the classroom! Start with subtilizing and the break down of numbers and move to computation strategies and then to fluency. Use for 5-10 minutes out of the day and see how different students see different numbers. They love these because they can never be wrong. These subtilizing cards make it fun by using hearts! I LOVE subtilizing and building number sense and students love when you use festive things outside of the box!
