Daily Warm Up!
Set a 2 minute timer. See how many questions you can answer before the time runs out! You don’t need to copy these equations out, just remember to number your answers from 1-15.
Try to get faster every day!!
- 5+__=5 2. 3+__=5 3. 3+__=4 4. 4+__=5 5. 6+__=6 6. 3+__=6 7. 5+__=10 8. 1+__=4 9. 9+__=10 10. 1+__=7 11. 5+__=9 12. 5+__=6 13. 4+__=8 14. 2+__=4 15. 5+__=6
Record your time or how many questions you were able to answer! See if you can beat it next time!
How did you go? Let me know if you need help!
Activity
See if you remember what numbers add up to 10.
6+__=10 __+7=10 0+10= 9+__=10 5+__=10 __+2=10
Now add up to 20.
11+9= 15+5= 13+7= 10+10= 18+2= 14+6= 12+8= 17+3= 19+1= 16+4= 20+0= 5+15= 9+11= 7+13= 2+18= 6+14= 8+12= 3+17= 1+19= 4+16= 0+20=
Challenge
Use what you know from above to fill in the blanks to make 20. Use the number line pic above to help if you get stuck!!
5+__=20 18+__=20 16+__=20 __+20=20 __+10=20 __+19=20 17+__=20 __+11=20 12+__=20 20+__=20 __+6=20 15+__=20 7+__=20 10+__=20
Are you getting the hang of adding to make 10 and 20?
How are you going at filling in the blanks?
I’d really like to hear about it in the comments section!!
