These 1st grade math worksheets cover both, with practice across the Common Core domains for the grade, from Operations and Algebraic Thinking (1.OA) and Number and Operations in Base Ten (1.NBT) to Measurement and Data (1.MD) and Geometry (1.G).
Students solve addition and subtraction word problems within 20, work with tens and ones in two-digit numbers, order and compare objects by length, compose two-dimensional shapes into new composite shapes, and find the unknown number in equations like 8 + ? = 11. Each topic lists the standard it targets, so you know exactly what a page practices before it reaches the copier.
Print a set for independent practice after a mini-lesson, assign a page as homework, or use the number patterns and place value sheets for morning work.
