Your work is by far the best out there!!! Every time I see something pop up from you, I get so excited! So thrilled this is now a bundle! Thanks!
We don't use Eureka anymore, but I have found that it brought the best number sense and math understanding. I continue to use the resources incorporated with our new curriculum for that reason. These are great to add to what we are using now in order to incorporate those strategies! Thank you!!
