Solving a 'More Than' Addition Word Problem

Khan Academy

A clear, step-by-step walkthrough of how to solve a mathematics word problem involving addition and comparison. The video features a narrator reading a problem about two characters, Emeka and Tom, who spin a numbered wheel to win a prize. The problem requires calculating Tom's number based on the clue that it is '15 more' than Emeka's number (17). The video breaks down the problem-solving process into distinct phases: identifying given information, translating words into a mathematical expression, setting up a vertical addition equation, and executing the calculation using regrouping (carrying). The narrator demonstrates place value concepts by explaining that 12 ones is equal to one ten and two ones. This resource is highly valuable for early elementary classrooms introducing two-digit addition with regrouping within the context of word problems. It explicitly models how to extract data from text, interprets the phrase 'more than' as an addition signal, and encourages checking the final answer for logical consistency.
