## Statistics: Steppin' Out

Icon:

Using this resource group, teachers can focus on the topic of statistics by having students construct box and whisker plots to analyze and compare data sets. This resource group is part of the Mathline Middle School Math Project.

## Number Forms

Icon:

Part of using base-ten numbers correctly is understanding how to express the same number in different forms. This video demonstrates how to express base-ten numerals written in standard form, unit form, expanded form, and number name.

## Maria Leiss: 8th Grade | Inside the Classroom: Math

Step inside Maria Leiss’ eighth grade math class. Get up close and personal with real-life approaches to pre-high school topics like linear equations, functions, and graphs.

## Argumentation and Review

Icon:

This video from Making the Case shows how teacher Nina Vasquez structures test review in her 12th grade AP Statistics Class at Everett Alvarez Jr. High School in Salinas CA. As her students work in groups and do peer grading, they both review and solidify their content knowledge, and refine their skill in making and critiquing arguments, supporting the Common Core Standards for Mathematical Practice.

## Foundation of Multiplication & Division

Icon:

Your child sets the foundation for understanding multiplication and division in second grade. The first layer in building this foundation is a concrete understanding. He will use objects as counters to create equal groups.

Making equal groups, drawing pictures, and using repeated addition all build a strong foundation for third grade, where your child will dive right into multiplication and division!

## Encouraging Debate

Icon:

In this video from Making the Case, teacher Chris Luzniak uses debate structures in his 12th grade pre-calculus class to engage students in argumentation and critique.

## Ideas in Action: Visit Other Classrooms

Icon:

In this video from Making the Case, math teachers Leticia Lopez and Eddie Torres plan lessons together, and later will observe each other’s classrooms. Visiting other classes provides a chance for teachers to listen for student arguments, to how they form conjectures, present reasoning and critique one another. Observing this in another teacher’s classroom can improve a teacher’s ability to implement the argumentation and critique standard in the Common Core Standards in Mathematical Practice.

## Regrouping to Subtract

This video addresses Common Core Grade 2 Standard Number & Operations in Base Ten: Use place value understanding and properties of operations to add and subtract.

## Overview: Perseverance in Mathematics

Icon:

Reflect on the meaning of perseverance and strategies for teaching it to students in this video from Keep Going! According to expert educators, perseverance is not a characteristic reserved for a special few. It’s something that all mathematics students can develop, practice, and improve.Recognizing that the brain can grow and stretch, teachers must help students understand that when they persevere, they are growing. When they struggle, they are getting smarter and becoming more resourceful mathematical problem solvers.Because students’ ability to persevere is intricately linked to their metacognitive abilities, teachers have to teach students how to reflect and what to reflect on. This video provides context about implementing Common Core Standard #1 for Mathematical Practice: “Make sense of problems and persevere in solving them“ in your classroom practice.
