The study aimed to develop an Instructional Aid in Mathematics for Grade 7 learners using TikTok application to help the learners easily understand the lesson. The study also aimed to assess the level of acceptability of the developed TikTok-Based Instructional Aid and comments and suggestions of Grade 7 Mathematics teachers for its further improvement. Based on the suggested topic by Grade 7 Mathematics teachers the TikTok-Based Instructional Aid contained “Solving Integers using the Basic Operations”. Descriptive method was employed in this study. The researchers used this method to identify the level of acceptability of the developed Instructional Aid in Mathematics for Grade 7 learners. The respondents were selected through purposive sampling technique that utilized two groups of respondents, they were Grade 7 learners and Grade 7 Mathematics teachers. In this study, the researchers found that the developed TikTok-Based Instructional Aid in Mathematics 7 is very highly acceptable with respect to the suggested topic by Grade 7 Mathematics teachers. This study concludes that in developing TikTok-Based Instructional Aid, the area should be more specific due to the brief duration of the TikTok application; there is still room for improving the learning of Grade 7 learners in solving Mathematics problems using this Instructional Aid. By using TikTok-based Instructional Aid student’s performance in Mathematics will also improve. Lastly, using that Instructional Aid the teachers' teaching competency and skills will be more refined.
