Today we practiced estimating square roots of non-perfect squares. We used perfect squares on either side to narrow it down to a good estimate. We read page 95-98 together and completed the Show You Knows. The assignments was p.99 #4-15. Next class we will do more questions with Pythagorean Relationship.
Last week the students learned about Pythagorean relationship. We completed page 92 #4-11 and page 93. #12-17. This week we will look at estimating square roots, pages 95-100, and then move on to more problems using Pythagorean relationship (p. 101-111).
We began learning about squares and square roots. Remember a number squared means you multiply the number by itself. For example 3 squared means 3x3=9. Square root means "What number multiplied by itself equals the given number?" For example, the square root of 36 is 6 because 6 times itself equals 36. This week the students were asked to master the squares and square roots to 100, then 225, then 400. A quick quiz for each will occur this week and early next week. The hand-out for this can be found below. The assignments this week were page 86, #17-23 . Tomorrow we will begin learning about the Pythagorean Relationship. We will complete pages 88-91 together, then the students will complete page 92 #4-7.
We finished our unit today on ratio, rate and proportional reasoning. Next class (Monday) the students will complete a practice quiz, then on Wednesday will complete the unit test. The information sheet is provided below, if you have misplaced it.
This past week the students learned about rates. The definitions for rates and unit rate can be found on pages 55 and 56 in the text book. The students looked at the example on pages 56-57 and completed the Show you know on page 57. They then completed Example 2 on page 58 before turning the page for the solution. They also completed the Show you know on page 58 and reviewed the key ideas on page 59. Finally, the students completed practice questions p. 60 #7-9 and p. 61 #10-15. Next week we will look at proportional reasoning. A quiz covering ratio, rate and proportional reasoning will occur at the end of next week or early the week after.
This week we began learning about ratio. The assignment today was p. 51-53 (#5 c and d, #6-15 and #17-18).
The students must all purchase a scientific calculator. They will not be allowed to use their cell phones as a calculator after this week. If you have any questions, feel free to email me at [email protected]. |
