Greetings! My name is Ms. Lanning, and I have personally developed and implemented this 4 square math model in my classroom. I can attest that this systematic approach is the greatest contribution to my student's understanding of math concepts and number sense. 4 Square Math is a research based spiral review of math skills that builds in depth and complexity. All material is CCSS aligned for Kindergarten Mathematics. Students begin the 4 square progression with identifying and practicing number recognition, and build to comparing quantities, composing and decomposing equations, and identifying flat and solid shapes. The implementation of 4-square in my classroom has created flexible thinking and encouraged organic math conversations. The inclusion of a pre and post assessment will support the identification of areas of strength and need. Written in an easy to understand format, this resource will boost math comprehension in the classroom for teachers who are looking for a math supplement, or at home for parents wanting to increase their child's math understanding.
