Math is Figure-Out-Able!

There's so much power to understanding subtraction that extends all the way to higher math. In this episode Pam and Kim discuss beginning steps to help students develop an understanding of subtraction, preparing them for success.Talking Points:How does I Have, You Need apply to subtraction?Subtracting across zeros is a beast! So what do we do?Where subtraction helps in multiplication, division and beyondUnderstanding removal versus differenceWhy is this important for higher math?What happens if we force kids into steps?What you can do to help your students?See Episode 150 for more about "Memorizing Subtraction Facts"Check out our social mediaTwitter: @PWHarrisInstagram: Pam Harris_mathFacebook: Pam Harris, author, mathematics education

Establishing a strong understanding of the area model also prepares students for more advanced topics all the way into college! In this episode, Pam and Kim describe how useful the area model is as a foundation for further understanding throughout a student's learning career.Talking Points:Using the area model builds intuition of the distributive propertyUsing and understanding the area model for fraction multiplicationParadigm shift for teachers to think about what students know about whole numbers and apply it to fractionsThe area model as a tool, not something that is sketched for every problemArea model inspired graphic organizer for polynomial multiplication, polynomial division, and conics                       See Episodes 146 and 147 for more discussion of the Area ModelCheck out the new t-shirt at https://www.mathisfigureoutable.com/merchandise Check out our social mediaTwitter: @PWHarrisInstagram: Pam Harris_mathFacebook: Pam Harris, author, mathematics education

The area model can do more than build Spatial Reasoning. It can help make sense of the major multiplication and division strategies! In this episode Pam and Kim use a Problem String to show how reasoning about area can build more sophisticated and efficient multiplicative relationships.Talking Points:Multiplication is about grouping groupsThe area model can help make sense of multiplicative relationships and propertiesChoose and celebrate efficient strategiesReasoning about area makes relationships pop so that the strategies are natural outcomes!See this blog for a picture of Pam's model in this episode: https://www.mathisfigureoutable.com/blog/ep147See Episodes 146 and 148 for more discussion of the Area ModelCheck out the new t-shirt at https://www.mathisfigureoutable.com/merchandise Check out our social mediaTwitter: @PWHarrisInstagram: Pam Harris_mathFacebook: Pam Harris, author, mathematics education

The area model is a great tool to help students develop multiplicative and spatial reasoning, but let's get clear on some things. In this episode Pam and Kim discuss some of the common misconceptions about the area model and show how it can be used help students make connections between area and multiplication. Talking points:What is an area model?Common misunderstanding around an area modelPlace Value Partial Products vs Smart Partial ProductsRote memorizing perspective vs Math-is-figureoutable perespectiveClosed/Discrete versus Open arraysArea models build spatial reasoning and connections of products to area and factors to dimensionsRatio Tables are better models for cranky computation problemsSee Episodes 129-133 for more about Ratio Tables and 147 and 148 for more about the Area Model.Check out the new t-shirt at https://www.mathisfigureoutable.com/merchandise Check out our social mediaTwitter: @PWHarrisInstagram: Pam Harris_mathFacebook: Pam Harris, author, mathematics education

There are a lot of small shifts needed in math education, and they can  have huge impacts. In this episode Pam and Kim talk about some of these shifts that will be included in the new mini workshop. This workshop will help you address the most important things to get right as a math teacher.Talking Points:Algorithms verses strategiesModels verses strategiesCommon vocabularyA few major relationships lead to the major strategiesProblem Strings versus Problem TalksMajor Strategies ebookCheck out the mini workshop https://www.mathisfigureoutable.com/miniCheck out our social mediaTwitter: @PWHarrisInstagram: Pam Harris_mathFacebook: Pam Harris, author, mathematics education
