Solving Addition Word Problems Using Bar Models

MatholiaChannel

This animated mathematics tutorial introduces young learners to the concept of using bar models to solve addition word problems up to the number 50. The video clearly demonstrates how to visualize textual information by converting word problems into graphic representations, bridging the gap between reading comprehension and mathematical calculation. It uses a step-by-step approach to model the problem-solving process, from reading the scenario to labeling the bars and performing the vertical addition. The content covers two distinct examples: a simple addition problem without regrouping (25 + 11) and a more complex problem requiring regrouping/carrying (18 + 27). Key mathematical themes include place value, vertical addition algorithms, identifying key information in text, and the specific mechanics of regrouping ones into tens. The use of the "Singapore Math" bar model approach helps students conceptualize the relationship between parts and the whole. For educators, this video serves as an excellent tool for visual learners who struggle with abstract equations. It is particularly useful for introducing the "part-part-whole" concept and for demonstrating the standard algorithm for addition with regrouping. Teachers can use it to scaffold lessons on word problems, showing students explicitly how to extract numbers from a story and organize them visually before solving.
