In Kindergarten, instructional time will focus on two critical areas: (1) representing and comparing whole numbers, initially with sets of objects and (2) describing shapes and space. More learning time in Kindergarten should be devoted to number sense than to other topics.
While the content learning goals describe the mathematics students should be able to understand and do, the first eight learning goals (The Standards for Mathematical Practice) describe how students should engage with these mathematical concepts and skills as they grow in mathematical maturity and expertise. Teachers will connect the mathematical practices to mathematical content in all mathematics instruction. These learning goals merit the most time, resources, innovation, and focus necessary to qualitatively improve the instruction, assessment, and student achievement in mathematics.
