Kindergarten, Math, Week 41

Monday

• Fractions: One-Fourth
• Practiced with manipulative "cookies". I put four cookies on a plate and asked her what part had blue frosting. She would write the answer.
• Then we switched and I wrote a fraction and she demonstrated it with the cookies.

Tuesday

• Calculator: Subtraction
• I wrote out 10 equations and had K. use the calculator to solve them and then write the answer.

Wednesday

• Fractions: Review

Thursday

• Game: Shape Lotto, see Math, Week 19 for instructions

Friday

• Problem Solving: Graphs
• We made a line graph of the temperatures from our weather journal in science
• Game: Three Pots, see Math Week 19 for instructions
• We finished early, and K. asked if we could play this game.

Kindergarten, Math, Week 40

Monday

• Fractions: One-Third
• Use manipulatives and stories to practice the concept of thirds
• Practice writing fractions
• When we first sat down to do this, K. had a cookie. I asked her to break it into 3 pieces. The pieces were not equal. We discussed that the cookie pieces were not thirds because they pieces were not the same size. She had 3 pieces, but not thirds.

Tuesday

• Calculator: Addition
• I wrote out 10 equations and had K. work them on the calculator and write down the answer.

Wednesday

• Fractions: One-Fourth
• Used manipulatives and stories to understand fourths.
• Worksheet to practice writing 1/4, 2/4, 3/4

Thursday

• Game: Location Words, see Math, Week 9 for instructions

Friday

• Problem Solving: Probability
• We played "1 Spinner" and "21 Marble Outcomes" (the old probability activity) at Johnnie's Math Page

Kindergarten, Math, Week 39

Monday

• Fractions: One-Half
• Practiced dividing things in half (tortilla, graham cracker, apple, etc)
• Practiced writing 1/2
• Reviewed what the denominator and numerator mean

Tuesday

• Calculator: plus 1, minus 1
• Practiced plus with the calculator: 1 + 1 (2) + 1 (3) + 1 (4) etc.
• Practiced minus with the calculator: 10 - 1 (9) - 1 (8) - 1 (7) - 1 (6) etc.

Wednesday

• Fractions: One-Third
• Used manipulatives I had printed for thirds (pizza, pie, chocolate bar).
• "One Tuesday we had pizza for dinner, and it was just Papa, you, and me, so we divided the pizza in 3 equal pieces. This is called thirds. If we each got 1 piece how much would you get? (one third) This Tuesday night I went to Bible Study, so I told Papa to eat my piece of pizza. How much did Papa get? (two thirds) Do this with all the manipulatives.
• Made a worksheet with four questions. How many pieces are yellow? etc. so K. could practice writing fractions.

Thursday

• Game: Fast Track (subtraction), see Math, Week 27 for instructions

Friday

• Problem Solving: Graphs
• Made a line graph.
• I printed a picture of chocolate candy from the internet.
• K. counted how many pieces there were of white chocolate (made tally marks), milk chocolate, dark chocolate, and chocolate with nuts.
• Made line graph with the information.

Kindergarten, Math, Week 38

Monday

• Fractions: Halves of a set
• We went into the kitchen and I pulled out sets of things: forks, recipe books, bowls, spices, etc.
• K. divided each set in half

Tuesday

• Calculator: Make numbers
• I said or wrote a number and K. punched it into the calculator
• Then she punched in numbers and read them to me

Wednesday

• Fractions: One-Half
• I had printed some manipulatives: a pizza, a pie, a chocolate candy bar (I put some figured contact paper that I had on the back side to make them durable)
• I showed these and we talked about one-half
• I had made a worksheet showing how to write 1/2. Explaining the denominator tells how many equal parts are in the whole and the numerator tells how many parts we are talking about. I had made four circles on the paper and divided them in half, coloring each side a different color. Then asked, "How many parts (of this circle) are yellow?" This gave K. the opportunity to write the fraction 1/2.

Thursday

• Game: Triangles, see Math, Week 31 for instructions

Friday

• Problem Solving
• Activity: Number Stories, see Math, Week 26 for instructions

Kindergarten, Math, Week 37

Monday

• Fractions: Equal Parts
• Used stuffed animals and a set of 24 pieces of pasta
• I put out 2 animals and had K. divide the pasta equally, then count and see how many each animal had.
• Then I put out 3 animals and had K. divide the pasta equally, and count how many were in each set.
• Then I put out 4 animals, etc.
• Then I put out 6 animals, etc.
• We learned that the more you have to divide something in, the smaller each set is.
• A good book for this concept is The Doorbell Rang by Pat Hutchins

Tuesday

• Calculator: What digital numbers look like
• I made a paper calculator and a strip of paper with the markings of calculator numbers
• Then I wrote a number and K. used a marker to trace how that number would look on a calculator.
• She got frustrated about half way through, so we took a break and read for a bit.

Wednesday

• Fractions: Halves of a Set
• We went into K.'s room and I put out sets of blocks, animals, etc.
• K. separated them into equal halves
• We learned that when you make a half there are two parts and each is equal

Thursday

• Game: Races, see Math, Weeks 25, 26, and 27 for instructions (addition)

Friday

• Problem Solving: Graphs
• I printed a picture of candies from the internet.
• K. counted how many there were of each color and made a bar graph.
