Smrt Sutrt Puzzles omine the fun nd ingenuity of puzzles with the repetition nd prtie kids need to mster their si sutrtion fts. Eh puzzle is omposed of two-step prolems in rossword-like formt. Skill Development This unique nd puzzling pproh tehes kids to: Sutrt single-digit numers quikly nd effiiently 2. Mster sums of 10 - foundtionl skill for oth ddition nd sutrtion 3. Develop their mentl mth skills y working with sums nd differenes in their hed 4. Think lgerilly y solving for missing ddends nd sutrhends 3 Levels of Diffiulty Green puzzles re the esiest nd fous on two foundtionl skills: sutrting single-digit numers nd mking sums of 10. Blue puzzles uild on the green puzzles nd hllenge kids to sutrt lrger numers efore mking sums of 10. Purple puzzles re the most diffiult nd dd hllenging twist. Students must think lgerilly nd work kwrds to find missing sutrhends - the numer tht is sutrted to get the differene. OVERVIEW

2 Puzzle Exmples! Use ONLY wet-erse mrkers. Any other mrker my permnently dmge the sheets. Green Exmple: Mke Aross Down Sutrt the first two numers: 5-2 = 3. Next, find the missing ddend: 3 +? = 10. Sine = 10, the nswer is 7. Sutrt the first two numers: 8-2 = 6. Next, find the missing ddend: 6 +? = 10. Sine = 10, the nswer is 4. Blue Exmple: Mke Aross Down Sutrt the first two numers: 14-9 = 5. Next, find the missing ddend: 5 +? = 10. Sine = 10, the nswer is 5. Sutrt the first two numers: 14-6 = 8. Next, find the missing ddend: 8 +? = 10. Sine = 10, the nswer is 2. Purple Exmple: Mke Aross Down Add the first two numers: = 13. Next, find the missing sutrhend: 13 -? = 9. Sine 13-4 = 9, the nswer is 4. Add the first two numers: = 12. Next, find the missing sutrhend: 12 -? = 9. Sine 12-3 = 9, the nswer is 3. OVERVIEW
