This is the first step to Make 60... add to 60.
Minutes to Hours is a Base 60 System.
Students need to compute the difference from provided minutes UP to the nearest hour.
This sheet is Level 3 - 1, 5 and 10 Minute Increments to 60. Students should get to the black star on the answer key when they have mastered the skill in 5 minutes!!!
Students should master 'Making 10' as well...to get to the nearest multiple of 10. That sheet is also on this TPT.
It just takes practice. The teacher can orally do this practice..."Name a value - for instance, 42... [Give the students some practice...work it through with them so they can see how easily it is add up to 50] students reply with 18 (i.e. 8 minutes to 50 PLUS 10 more minutes to to Make 60). This takes little practice, but the numeracy and number sense is amazing! I have had entire 5th grades that can do this skill within 4 to 5 days of practice in class...a quick homework of this sheet. Assess them once they are skilled with either attached sheet. It is just a structured practice session from a skilled teacher that makes all the difference with children.
Example: if a student is given 4:26 AM and asked to find the elapsed time to 6:13 AM. The first step is to compute the minutes to 5 AM. In this case, it is 34 minutes - 4 minutes to 30 and 30 MORE minutes to 5 AM - for a total of 34 minutes. Then, the problem is quite straight forward...hours to the hour in question...1 hour, in this case. 13 more minutes to 6:13 AM. Hence, the total elapsed time is 1 hour 47 minutes.
But, the student MUST Make 60 to be profiicient at this skill. It just takes practice. It is recommended the teacher include this skill in a daily Spaced Repetition System (SRS) each day. There is a white paper that explains this pedagogical process on this website that delves into details on this instructional method, if the eduacator is NOT familiar with it. It is a game changer in the classroom.
Best to you are your students.
