This this task about mixing paint requires students to graph ratios on a coordinate plane. It is a standard language in ratio problem.

Using ratios to compare quantities Mathematics Instructional Plans (MIPs) help teachers align instruction with the Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom

In this module, students are introduced to the concepts of ratio and rate. Their previous experience solving problems involving multiplicative comparisons, such as 'Max has three times as many toy cars as Jack,' serves as the conceptual foundation for understanding ratios as a multiplicative comparison of two or more numbers used in quantities or measurements. Students develop fluidity in using multiple forms of ratio language and ratio notation. They construct viable arguments and communicate reasoning about ratio equivalence as they solve ratio problems in real-world contexts.

Students will find helpful resources for learning and practicing math skills and processes in this eMediaVA collection.

This collection has resources organized by grade level teachers can use to teach math.

In this self - checking activity, students will answer questions related to expressing a ratio in one of the three forms. As students enter their answers, a part of the picture will be revealed. Once students complete the self - checking part of the activity. they will complete a reflection question explaining how the relationship changes when the numbers are switched.  

In this activity, students will use different strategies to help understand and represent ratios.
