The worksheet titled "Reviewing Basic Operations: Addition Trees, Missing Addends, and More" is a great way to give your students grade-level appropriate math practice that incorporates critical thinking skills.

Worksheets include basic addition problems in different formats to give students practice solving problems horizontally and vertically. Students add larger numbers in higher grades, and some addition problems contain missing addends. Other problems have missing digits that students have to fill in.

Worksheets include addition and multiplication trees as well as word problems for students to solve. There are also math minute sections where students can see how many problems they can answer in 60 seconds.

All math problems are enclosed in their own square or rectangle with room for students to write their answer or work out the problem.

Students can learn a lot about how numbers relate to each other and the mechanisms of different operations when they are exposed to math problems in a variety of ways. For example, students can answer addition problems that are written horizontally, but they should also answer problems that are written vertically. Addition and multiplication trees are a great way to show how numbers are combined and split apart.

Even very young students can solve addition problems with a missing addend. Older students can find the missing digits in three-digit addition problems. Timed math problems can help you assess how well students understand a particular math concept, while word problems can help support problem-solving skills.
