Second Grade: Addition and Subtraction of 2-digit and 3-digit numbers
Share this:
In second grade, building addition and subtraction fluency is crucial. Therefore, I’ve created another Math Made Fun unit to just this, but this time for 2-digit and 3-digit numbers up to 1,000. While addition and subtraction of 2-digit and 3-digit numbers is an extension of concepts that have been taught in the previous unit, Unit 4 is packed with plenty of hands-on practice to help students master the ability to add and subtract larger numbers.
In this math unit on Addition and Subtraction up to 1000, students will learn to:
*Add up to four two-digit numbers using strategies based on place value and properties of operations
*Add and subtract within 1000, using concrete models or drawings and strategies based on place value
*Add and subtract within 1000, using properties of operations
*Add and subtract within 1000, using the relationship between addition and subtraction
*Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones
*Understand that in adding or subtracting three-digit numbers, sometimes it is necessary to compose or decompose tens or hundreds
*Mentally add 10 or 100 to a given number 100-900, and mentally subtract 10 or 100 from a given number 100-900

HOW DO I ORGANIZE THE UNITS?
I chose to store the math centers in Sterilite bins, because they don’t take up too much space. It is a tight fit, but I find that they work nicely for me. However, if you choose, you could store the centers in a larger container as well. Within the bin, each math center is stored in a gallon sized ziplock baggie. Since Unit 3 has 49 math centers, I found it helpful to split up the centers into 2 bins.
