Watch The Pride of Walnut Grove

Mary enters a statewide math competition, but Charles can't afford to pay the travel expenses necessary for her to compete. The entire town council foots the bill with great pride in her. This causes Mary to worry she will let them down. Her return to Walnut Grove shows her that the town is proud of her whether or not she comes first. Although this does not happen, she does get very close, finishing in second place. When she returns to Walnut Grove, Mr. Hanson and the whole town are very proud of her anyway, and Mr. Hanson states how happy he is for Mary putting Walnut Grove on the map of Minnesota.
