This package includes the four sets of calendar pieces that we would use for December, January, February, and March based on the Common Core Standards Curriculum Map for Georgia. If your state does the same units in the same order, these would work in this order for you as well. The goal is always to have the calendar pieces practicing concepts that are either previewing future concepts or reviewing past concepts. That way there is maintenance as well as background knowledge being built for future units of study. If your curriculum map is in a different order, you may want to rearrange the months. Included are: 4th Grade Quadrilaterals, Triangles, Fraction of Whole, Time; 4th Grade Equivalent Fractions, Geometric Figures, Fractions; 4th Grade Angles, comparing Fractions, mass, Prime/Composite; and 4th Grade Area, Perimeter, Capacity, Protractors. Please send us any questions you may have as to what pieces may work for you. From Julie Nelson of Nelson-Bonn LLC.
