Self-checking task cards for students to practice adding 3 and 4 digit numbers, to the thousands place, with regrouping. This product includes 32 task cards, along with the answers printed in light grey on a separate page (print front to back on cardstock to use as a self-checking activity). There is also a "show your strategy" recording page for students to work out the problems and show what strategies they're using.
I love to have my students solve a problem using multiple strategies (ie. open number line and expanded form), showing their work on the same page so they can see how the different strategies work. The recording page is a great way to do this!
These task cards are perfect for an independent or partner math center, for a whole group warm up or quick practice, or an exit ticket. You can even use them as a low-prep option if you have parent volunteers or other classroom support.
