Great to work on number sense! Showing multiple ways to get a number has students demonstrate understanding of number sense. After scouring through many number of the day pages, I decided to create one to fit my needs in first grade. You can use it as a whole sheet; it is also formatted so that it can be cut in half, should you choose to. The number equations is a box that works on differentiation: while some students need more guidance, this allows my challenge students to do complex problems: multiplying, adding 3,4,5 numbers together, etc. I use the numbers off of our calendar, that way, we do not get too high and we revisit the numbers every month.
