1st Grade Common Core- Need a medium that supports the mathematical practices. Need a practice sheet that provides room for students to draw out their thinking and model their math? Check out these 6 pages...they include adding practice with models and number lines, skip counting by 10s ( 24, 34, 44 etc.) and two digit plus one digit using the decomposition of the single digit to get to the next 10 (28 + 6 by adding 28 + 2 to get to 30 then 30 + 4 = 34)

1OA1 Common Core practice for word problems with missing addends. Students can draw out known information and solve for the sum/difference or unknown. Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

Students add (sums below 12) using a number line. This adds another modality of understanding addition. Students can start with the higher number and count on by using the visual number line. Common Core understanding requires students to draw, build, explain, etc., and emphasizes the importance of using a number line repeatedly. Students can make up their own number sentences as well. This assignment will lead nicely into using different adding strategies (decomposing numbers etc.) and with d

This Common Core resource covers six different aspects of of 5NBT5 (fluently multiply multi-digit whole numbers using the standard algorithm). To fully understand the standard algorithm, use this resource to help bridge the gap from abstract to concrete. Using the area model (portioning) students create visual connections. Word problems are included. Also exposing students to the FOIL method encourages use of expanded form and prepares them for future use of this process. Also included is a ment

2OA4 Common Core Practice- Students use this medium to write addition sentences for various arrays. They can make up their own as well.

Use this Common Core resource to help students understand addition properties, equalities, and missing addends. Students should draw dots or shapes under each number and visually be able to see how 3+2=4+1 etc. Sheets 1 and 2 have one sum (left or right of the equal sign) and sheets 3 and 4 have 2 and 3 addends on each side of the equal sign. Use whole class, in a guided math group or for a math center.
