Addition Task Cards: Adding with Expanded Form
I made this file out of necessity for my own students, who needed to practice adding numbers by using expanded form. Decomposing numbers, or showing the value of each digit, is an important strategy to teach young mathematicians.
I like to post these addition problems in different areas of the classroom. My students “roam the classroom” to answer each addition problem as I work with a group of students or walk around to assist students.
File includes 28 task cards, an answer key, and an anchor chart to display for how to use expanded for to add.
Specific standard addressed:
Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
