18. Life Performance Outcome I am a mindful, self-directed learner and role model, consciously expressing my Faith.

19. Essential Performance Outcome Take time to plan, pray, and have quiet time every day and encourage others to do the same.

20. Intended Learning Outcome Add mentally 2-digit and 1-digit numbers without or with regrouping using appropriate strategies, focusing on accuracy and speed in quick mathematical computations. Estimate the sum of 3- to 4-digit addends and reflect on the importance of making reasonable estimates in problem-solving, much like organizing one’s thoughts before taking action.

21. 35 + 2= ? 37

22. 82 + 4= ? 86

23. 27 + 7= ? 34

24. 81 + 8= ? 89

25. 64 + 6= ? 70

26. 37 + 10= ? 47

27. 45 + 21= ? 66

28. 63 + 36= ? 99

29. Processing Questions: What helped you solve the problem faster—grouping numbers, visualizing, or something else? How do you think practicing quick mental addition can help you in your daily activities, like organizing your time or solving simple problems?"

30. ? ESTIMATING THE SUM

31. Processing Questions: Why is it important to make a reasonable estimate before adding large numbers? Can you think of a time when making an estimate helps you plan better, like knowing how much time you need to complete your homework? How can estimating help you make better decisions in your daily life, like knowing how much something will cost or how much time it will take?
