This packet is the perfect activity set or assessment tool for teaching number sense within 20. It includes:
-addition on a number line
-subtraction on a number line (counting back)
-subtraction on a number line (counting up)
-a complete teacher guide for each number line strategy (that I also use as a parent guide)
-balancing equations (ex: 8 + ___ = 14)
-stating whether or not equations are true or false
-AND a complete summative assessment assessing every skill!
