This set of slides (contains 18 slides) align with multiple CCS standards for first and second grades: 1.MD.C.4; 1.NBT.A.1; 1.OA.A.1; 1.OA.B.4; MP1; 2.NBT.B.5; 2.OA.A.1; 2.OA.B.2. This is a great way to teach the use of Math Journals and problem solving in first and second grades. (Can also be used with other grade levels, depending on the needs and abilities of your students.)

Skills included are:

• counting
• tallying
• adding one step word problems
• subtracting one step word problems
• focus given to writing an equation and using a symbol

for the unknown number.

I love to use these slides for whole group instruction. I display one slide at a time, read aloud the slide, and discuss strategies and/or tools that students could use to solve the problems. Some slides are for verbal review only, like the counting or tallying slides, which encourages critical thinking. Other slides will require students to think of strategies or methods to use to solve problems. Students should write an equation and use a symbol for the unknown number, as prompted on the slides. These slides can be printed, size reduced, and glued into math journals, allowing teachers to have a record of student work and problem solving ability.
