This post explains and give practice opportunities related to TEKS 3.7C:
determine the solutions to problems involving addition and subtraction of time intervals in minutes using pictorial models or tools such as a 15-minute event plus a 30-minute event equals 45 minutes
Time intervals ask students to start at a certain time and calculate a stopping time based on how much time went by.
Between 2016 and 2022 (including redesign practice), this supporting standard has been tested 5 times on the STAAR test. Videos explaining each problem can be found below.
