NY-1.NBT.4: Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.

About Media4Math
Our Mission
Media4Math's mission is to educate 21st-century students in real-world applications of math with digital technology. We bring math to life in your classroom with a rich blend of resources to inspire your students to learn. Our philosophy is that the procedural side of math is a prerequisite to using it, but we also find that real-world math applications can provide motivation and even inspiration for math students. Math is its own language and it has important stories to tell. While many of our resources are for procedural skills, there are many resources that are real-world applications of math. Some of these resources rely on partnerships with other educational publishers.
