Math U See Beta Subtraction (2nd grade)
Class Description:
In this 2nd grade math class, the student will use Math U See Beta to build on the foundation learned in 1st grade by applying students’ mastery of single-digit addition and subtraction to multiple-digit addition and subtraction. An important concept to aid in this is place value. Math U See is a curriculum that uses manipulatives to illustrate and teach math concepts. Student work toward building understanding by using a multi-sensory, mastery-based approach. (
Learning Materials: Main Curriculum:
Math U See Beta Instruction Pack
Math U See Beta Student Kit

Learning Goals/Performance Objectives: 2.2.C Add and subtract two-digit numbers efficiently and accurately using a procedure that works with all two-digit numbers and explain why the procedure works.
2.2.D Add and subtract two-digit numbers mentally and explain the strategies used.
2.2.H Name each standard U.S. coin, write its value using the $ sign and the ¢ sign, and name combinations of other coins with the same total value.
2.3.A Identify objects that represent or approximate standard units and use them to measure length.
2.3.D Describe the relative size among minutes, hours, days, weeks, months, and years.
2.4.B Collect, organize, represent, and interpret data in bar graphs and picture graphs.
Learning Activities: The student will complete 3-4 lessons (units) per month, per the timeline below. Each lesson consists of video instruction, 3 practice worksheets on new material, 3 systematic review worksheets, an activity page (optional), and a test.
