I hope everyone had a restful, fun break! I know I really enjoyed catching up with friends and family and getting to sleep in. :)
This week we are starting our Fossils unit in Science. Today we discussed what fossils are, why we study them, and what we can learn from them. Tomorrow I will be bringing in some real plant and animal fossils for the students to explore and discuss. Please ask your student what kinds of fossils we have been exploring! The test for this unit is going to be Tuesday, 12/15.
In Math we are continuing our unit on Area, multiplication and division strategies, graphing, measurement, and word problems. Our Unit 3 test will be on Monday, 12/14. The related standards are:
Solve problems involving the four operations, and identify and explain patterns in arithmetic.
MGSE3.OA.8. Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.1
1
MGSE3.OA.9. Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations.2 For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.
Represent and interpret data. MGSE3.MD.3. Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step "how many more" and "how many less" problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
MGSE3.MD.4. Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters.
Geometric Measurement: understand concepts of area and relate area to multiplication and to addition.
MGSE3.MD.5. Recognize area as an attribute of plane figures and understand concepts of area measurement.
a. A square with side length 1 unit, called "a unit square," is said to have "one square unit" of area, and can be used to measure area. b. A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.
MGSE3.MD.6. Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
MGSE3.MD.7. Relate area to the operations of multiplication and addition.
a. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.
b. Multiply side lengths to find areas of rectangles with whole number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.
c. Use tiling to show, in a concrete case, that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning.
Also, please help your student get fluent in his/her multiplication facts 0-12. We are continuing to have timed tests and students who pass all their facts will be rewarded abundantly at our ice cream social the last week before the break. :) Thank you for all of your support!
