Math - January
We are coming to an end with Unit 3 !!!!
For Mrs. Rosales and Mrs. White's math class, the assessment will be either Thursday or Friday. How do I know if my child is prepared? Your child will receive a homework sheet that will review all the skills that they need to be successful. Please make sure this is completed by Thursday to assure that they are ready for the assessment.
Unit 4 will begin the week of the 25th.
-Identify whether numbers are even or odd
-Identify geometric shapes and their attributes: angles, vertices, faces, sides
-Create a rectangular array and write an expression to match it. There are 4 rows and 3 columns of tiles. 4+4+4 = how many tiles? This concept prepares your child to begin multiplication.
-Partition circles and rectangles into two, three or four equal shares and describe the shares by using halves, thirds and fourths.
Unit 3
We have been using a number line to add and subtract two-digit numbers. Please give your child an equation such as 24+62 then ask them to draw a number line and add. Try a subtraction equation such as 62-24. To add they should begin on the left side of the number line and to subtract they should begin on the right side and hop backwards.
This week we are learning more strategies to add and subtract. We are using place value to draw the tens and ones and add them together. When subtracting they only draw the first number and subtract by crossing out. We will also learn the break apart strategy. To add 24+62 first add the tens 20 + 60=80 then add the ones 4+2=6, last add the tens and ones together 80+6=86.
The next two weeks we will apply our strategies to word problems. We will use a Mnemonic tool called CUBES.
C-Circle the numbers in the word problem.
U-Underline the question.
B-Box in the key words such as left, total, altogether, etc
E-Write an equation to solve the problem.
S-Solve the problem using one of the above strategies and show your work.
At this time please, refrain from teaching your child the algorithm of carrying and borrowing. We want our students to develop a solid understanding of the number system first.
You can also be working with your child on telling time to the half hour if needed. If they have mastered time to the half hour, then begin telling time to the quarter hour.
Also your child should be able to count a collection of coins to 50 cents at this time. Let them count your change for you using real coins.
Ms. Davis' Math Class
Homework will be due every Monday. The homework consists of problem solving activities that will require students to use skills they have learned and practiced in math this school year.
Students will learn more about arrays and how they are related to addition and multiplication equations. Students will make arrays to represent equations. They will also read arrays to solve equations.
Students will create multiplication equation charts and find relationships between different multiples. For example: 4x8=32 and 8x8=64 (The multiplication equation is doubled and so the product is doubled 32+32=64) They will also solve multiplication and related division story problems. Students will use their knowledge of multiplication and arrays to complete a problem solving project.
Vocabulary: arrays, expression, rows, columns, dimension, prime numbers, square numbers , product, multiples
