Help your students achieve addition fact mastery without a timer... without stress.. rather by encouraging them to set strategy based goals! Each bookmark lists a set of facts that ask the student to figure out what they have in common (i.e. make tens, count ons, doubles, etc). Students can use as a checklist or bookmark while learning facts and check in with you when they are ready to prove they've mastered them! See my spreadsheet and other products to help develop a stress free, more engaging way to master basic facts!
