The math focus of this resource is practicing addition using doubles and doubles minus one. These strategies are especially important for first and second grade students because they build number sense and help children move beyond counting one by one. For example, when solving a doubles minus one problem such as 8 + 7, students are encouraged to think: 8 + 8 = 16, so 8 + 7 = 15. This kind of reasoning strengthens mental math skills and supports long-term fluency.
Students begin on a simple home page where they click on a symbol to be taken to a random slide. Each slide presents an equation that is either a double or a doubles minus one problem. Students solve the equation, record their answer if desired, and then check their work by touching or clicking on their chosen answer. Immediate feedback is built right in. When students select the correct answer, a cheerful “Way to Go!” slide appears. If an incorrect answer is chosen, students see a gentle and encouraging “Try Again, You’ll Get It Next Time” message. This self-correcting feature allows students to learn from mistakes in a supportive way while building confidence and independence.
Teachers may also choose to extend engagement by using the included tally or points options. Students can tally correct answers on a tally slide projected on an interactive whiteboard, or teachers can print and copy the black-and-white points slide for individual student use. These options make it easy to adapt the activity to different classroom routines and learning environments.
Like all Learning Harbor Resources for Teachers activities, this adding doubles and doubles minus one resource is aligned with Common Core State Standards and designed to support effective instruction across a variety of settings. It works beautifully in traditional classrooms, homeschool environments, and tutoring sessions. The paperless format saves time, reduces prep, and keeps materials organized, while the interactive design helps students stay focused and engaged.
This Adding Doubles and Doubles Minus One resource is especially helpful for first year teachers who are building their instructional toolkit, as well as experienced teachers who value dependable routines that work year after year. It fits seamlessly into math stations, small groups, intervention, enrichment, and independent practice. Students gain valuable practice not only in math but also in basic technology skills as they navigate slides and click to respond.
