We believe the math classroom can be a joyful place where students discuss their thinking and share ideas with each other. This workshop focuses on providing opportunities for reasoning and addressing common misconceptions which arise in fractions, decimals and integer work. We provide building blocks that solidify mental images for students. Students who struggle with fraction, decimal, and integer concepts may not have used concrete models and pictorial representations as part of their learning. Instruction without modeling tends to focus on the use of equations and algorithms to abstractly represent math concepts. This workshop introduces activators which put visual models at the forefront in helping teachers and students anchor these concepts concretely. Speakers will teach a routine of building on student thinking through visual models. Models of how to record student thinking and provide clear instructional building blocks will be shared. Participants will experience hands-on and visual models to support their thinking around these often underdeveloped topics. Then they will practice recording student thinking that allows them to share students' ideas with the class to promote discussion.
