I have created this mini chart that my students can use when they need to solve word problems (I have an anchor chart displayed in the classroom of the same thing but my students often forget to use it). My students sometimes forget which key words help them to add or subtract so I added that to the bottom of the chart.
I printed mine out onto cardstock and laminated for durability.
I leave it inside their group's math bin and when it is time for math, the group captain brings over the math bin with this chart inside (along with other manipulatives).
You can tape it onto their desk to use as a reference or have them keep it inside their math folder.
