Toolkits are just like checklists--but with a twist. Have students solve a word problem directly next to their checklist. This juxtaposition gives students a visual reference to help them when using their checklist. Toolkits should be kept in a spot where students have access to them at all times. My students kept theirs in a folder along with other strategies. Tool kits should be added to as the year goes on, becoming a source of reference for students to have access to.
Toolkits are very helpful when teaching a variety of strategies in math. I also used them to teach specific skills, for example, solving multiplication using an open array. Really, anything that needs to be broken down step-by-step for a student can have a toolkit.
