Virtual Sessions for Add/Sub Strategies
This session demonstrates how to have students create and use number bracelets to help develop relational understanding between the parts and whole.
Number bonds provide a visual representation for the parts and whole so students can better understand the relation between the 3 numbers. This helps understand the inverse relationship between addition and subtraction.
This session connects bonds to branching, Branching is simply a decomposing strategy that allows students to add in friendly "chunks", using landmark or benchmark numbers to efficiently add numbers.
This virtual session will show you the power of branching with landmark numbers & fractions. Decomposing in friendly ways to get to the nearest benchmark fraction of 1/2 and 1 whole can be an efficient strategy for adding fractions.
This virtual session will show you the power of branching with landmark numbers & fractions. Decomposing in friendly ways to get to the nearest benchmark fraction of 1/2 and 1 whole can be an efficient strategy for adding fractions.
This virtual session will show you how decomposing and branching can be a powerful strategy when working with different measurement units as well as subtraction. Getting to landmark numbers such as 12 to equal 1 foot, or 16 ounces for 1 pound provides students with flexibility in working with these numbers and measurement units.
This virtual session will provide you with an understanding of how to use an Open Number Line strategy to solve and show your way of thinking for addition problems.
This video will show you how to use an open number line to subtract. An open number line can be used as a strategy to find the solution as well as a tool to show your mental computation. This video includes examples of "counting back to subtract". However, in Session 8, I will show you how to "add up" to subtract on the number line.
This sesssion shows you the real power of the number line as it builds the understanding of the inverse relationship. For many kids, adding up to find the difference or unknown is much easier than counting back.
Compensation is a strategy in which numbers are adjusted to created simpler problems. This session focuses on addition and compensation. Student examples are provided.
Session #10 will provide you with some methods for helping kids utilize and understand compensation when subtracting. Engaging students in this strategy in a way that includes "sense making" rather than "step following" is critical!
This video shows some examples of the Place Value Break Apart strategy that many teachers connect with NBT. This strategy allows students to utilize their understanding of place value when adding and subtracting.
