Bar Models for Addition and Subtraction is a free printable Grade 1 mathematics worksheet that helps students connect visual part–whole models with addition and subtraction equations. Students identify whether to add or subtract, find a missing part, complete number sentences, and determine which equations match a bar model or number bond. The 12-item worksheet combines one drawing task with multiple-choice, multiple-select, and fill-in-the-blank questions. It gives students practice recognizing related addition and subtraction situations, including selecting all equations represented by the same bar model and identifying an equation that does not match. This format supports both visual reasoning and accurate operation selection before students solve independently. A complete answer key is included for efficient checking and feedback.

This Grade 1 worksheet teaches students to use bar models and number bonds to identify the whole, the parts, and a missing part, then choose addition or subtraction to represent the relationship. Its 12 items include a drawing task, multiple-choice questions, a multiple-select item, and a fill-in-the-blank task that require students to complete number sentences and match equations to visual models.
Begin by modeling how a bar model shows a whole divided into parts, then ask students whether the known quantities require finding the whole or a missing part. Work through one model together by writing both the operation and equation, and use the worksheet’s matching and “does not match” questions to discuss why different equations do or do not represent the same model. Finish with the drawing item so students create or complete a number sentence from the visual relationship.
Watch for students choosing addition when the whole and one part are known, or subtraction when the parts are known and the whole is missing. Students may also select an equation that uses the correct numbers but does not match the part–whole structure, overlook the word “NOT,” or choose only one valid equation in the multiple-select item instead of checking every option against the bar model.
Wayground provides this worksheet as both a printable PDF and a digital quiz, with a complete answer key for checking the drawing, operation-selection, equation-matching, and other responses. Printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable option also supports classrooms that are reducing screen time.
Use the worksheet’s Advanced Settings to adjust font spacing and font size so the bar-model questions, answer choices, and equations are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language when that better supports students working through the visual models and operation choices.
