I love how these come in a variety of levels. The first two levels were perfect for my kids working on counting and beginning addition. The first level is basically just counting up all the dots to come to the total.
The next level up is starting with one number and counting on using the dots (i.e. "8.......9, 10, 11, 12)".
These hardest ones were definitely a challenge for my kids, but they were a great, new way of working on addition. And, after some practice, my students totally got it and did great! So, thanks to The Happy Teacher for these great worksheets...my kids loved them! Definitely check out her blog for more great ideas and resources (http://thehappyteachertpt.blogspot.com/)!
