We have finally started a new unit on multiplication. The focus of our instruction is not how to multiply (since they already should have the basic concept down), but how to multiply using various methods, pictures, manipulatives, etc.
These are the HISD objectives we are focusing on this week:
MATH 5.3D- Identify common factors of a set of whole numbers using a variety of strategies and manipulative
MATH 5.2B- Use multiplication to solve problems involving whole numbers (no more than three digits times two digits with technology) applying array/area models to multiplication algorithms.
MATH 5.5B- Identify prime and composite numbers using concrete objects, pictoral models, and patterns in factor pairs.
The unit should end before Thanksgiving Break.
