The purpose of this research was to strengthen students' foundation of grammar in sentence construction. The problem statement is that students are unable to perform well in the English language classes, particularly in constructing simple sentences. Thus, this research examined whether 'Wheel Of Grammar' (WOG) is able to help students in constructing grammatically correct simple sentences. The rationale is to ensure students' confidence in the use of basic rules of Subject-Verb Agreement in sentence construction. Fifteen Form 5 students were chosen as sample based on their diagnostic test and first middle-semester examination results to avoid any biasness. The research used mixed-method design where quantitative data from pre- and post-tests were used to measure the outcome. To triangulate data findings, responses from the informal interviews and classroom observations were taken into consideration. The students' response reflects the improvement in sentence construction. They were able to apply correct basic rules of Subject-Verb Agreement, the right usage of tenses and Verbs-To-Be in the tasks. Grammar lessons became less stressful as they could easily search for answers in a fun and creative way.
