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.

Common Core Support for 1OA7-This medium provides practice for students to model equalities/inequalities.

3NBT2 Calls for students to be fluent with different methods of addition and subtraction. This Common Core resource emphasizes subtraction using number lines, base 10 shapes, and standard form. Numbers are below 250- great resource for introducing the number line concept (using expanded form) and regrouping using base 10 shape drawings. There are 4 sheets with 3 problems on each with plenty of room for students to draw out their work.

Using this resource to have students draw out both sides of the equal sign to help ingrain the meaning of the equal sign (both sides having equal value). This important concept will help build deeper understanding when it comes to finding the missing number (1OA8). Once they have drawn out both sides (ideally using sets of dots for ease in recounting-and helps with counting by 2s eventually), they can circle "equal" or "NOT equal". Students can also fill in their own equality sentences on the
