Question 23: Place the numbers 6,7,8,9 and 10 in the circles so that the sum on every line was equal to 24.Prediction:I predict I will need to use addition to solve this problem. Clarification: I have nothing to clarify

Solution: 1. Place a ten at the very top bubble(blue) 2. Find out what 10 + 5 equals.(15) 3. Find out what you add to 15 to get to 24.(9) 4. put the 9 in the left over bubble on the right hand side. 5 find out what 2 numbers equal 14 out of 6,7 or 8.(6+8) 6. place the 8 and 6 in the two left over bubbles on the left hand side. 7. now put the left over 7 in the last bubble Summary: I used the strategies test all possibilities, break it in to manageable parts and guess, check and improve.
