I purchased these number talks after noticing my new school’s math curriculum doesn’t provide good opportunities for students to talk about math. I love that these are easy for me to use and implement and spark good conversation among students. Thanks for creating an amazing product!

Great resource for number talks. Used with Kindergarten to get them to discuss what they saw in the dot patterns. Recorded together different ways to make the number represented by the dots.
