17. Reasoning Mind Academy: Unit Conversion Great! So, how do we actually convert?! Step 1: Write your. (Which unit did they give me? Which unit am I missing?) Step 2: the conversion on your STAAR formula chart. Step 3: Make a using the conversion formula. (Hint: “T”) Step 4: if you need to go from small → LARGE or LARGE →small. Step 5: or. Step 6: Write your in your answer!

18. Reasoning Mind Academy: Unit Conversion Great! So, how do we actually convert?! Step 1: Write your __information. (Which unit did they give me? Which unit am I missing?) Step 2: Find the conversion on your STAAR formula chart. Step 3: Make a t-chart/table using the conversion formula. (Hint: “T”) Step 4: Decide if you need to go from small → LARGE or LARGE →small. Step 5: Multiply or divide. Step 6: Write your __units in your answer!

19. Reasoning Mind Academy: Unit Conversion Example 1) On a baseball field, the distance from home plate to first base is 90 feet. How many yards is it from home plate to first base? Remember: Big to small, multiply them all. Small to big, divide you did! Using your steps written in your notebook, what would we do to find our answer?

20. Reasoning Mind Academy: Unit Conversion Example 1) On a baseball field, the distance from home plate to first base is 90 feet. How many yards is it from home plate to first base? Step 1- Write your information. -Which unit did they give me? Feet -Which unit am I missing? Yards

21. Reasoning Mind Academy: Unit Conversion Example 1) On a baseball field, the distance from home plate to first base is 90 feet. How many yards is it from home plate to first base? Step 2- Find the conversion on your STAAR formula chart. 3 feet= 1 yard(s) 1 yard(s) = 3 feet

22. Reasoning Mind Academy: Unit Conversion Example 1) On a baseball field, the distance from home plate to first base is 90 feet. How many yards is it from home plate to first base? Step 3- Make a t-chart/table using the conversion formula FeetYards 31 90?

23. Reasoning Mind Academy: Unit Conversion Example 1) On a baseball field, the distance from home plate to first base is 90 feet. How many yards is it from home plate to first base? Step 4- Decide if you need to go from small → LARGE or LARGE →small. small → LARGE

24. Reasoning Mind Academy: Unit Conversion Example 1) On a baseball field, the distance from home plate to first base is 90 feet. How many yards is it from home plate to first base? Step 5- Multiply or divide. FeetYards 31 90 ÷ 3 30

25. Reasoning Mind Academy: Unit Conversion Example 1) On a baseball field, the distance from home plate to first base is 90 feet. How many yards is it from home plate to first base? Step 6- Write your units in your answer. 90 ft. = 30 yd. It is 30 yards from home plate to first base. Remember: Big to small, multiply them all. Small to big, divide you did!

26. Reasoning Mind Academy: Unit Conversion Ex 2) Length: 2 mi = yds Ex 3) Length: 800 m = km Remember: Big to small, multiply them all. Small to big, divide you did!

27. Reasoning Mind Academy: Unit Conversion Ex 2) Length: 2 mi = ____3,520 yds Ex 3) Length: 800 m = 800,000 km Remember: Big to small, multiply them all. Small to big, divide you did!

28. Reasoning Mind Academy: Unit Conversion Ex 4) Capacity: 12 gal = c Ex 5) Capacity: 37,000 mL = L Remember: Big to small, multiply them all. Small to big, divide you did!

34. Reasoning Mind Academy: Unit Conversion Example 10) There are 15 students in a science class. Each student will need 125 mL of pond water. There are 2 L of pond water in the science kit for the whole class to use. If each student receives how much they need for the experiment, how many milliliters of the pond water will be left over? Remember: Big to small, multiply them all. Small to big, divide you did!

35. Reasoning Mind Academy: Unit Conversion Example 10) There are 15 students in a science class. Each student will need 125 mL of pond water. There are 2 L of pond water in the science kit for the whole class to use. If each student receives how much they need for an experiment, how many milliliters of the pond water will be left over? 15 125 mL = 1,875 mL 2L = 2,000 mL 2,000 mL - 1,875 mL = 125 mL Remember: Big to small, multiply them all. Small to big, divide you did!
