Second Grade, Math, Set Six

Addition

• K. completed six addition problems (three addends to ten thousands place with renaming). Then she marked which sums were odd or even, compared the sums using the < or > signs, and rounded to the nearest ten or hundred.
• We played games from the books, Adding and Subtracting Book 1 and Book 2 by Ann Montague-Smith.
• We practiced the order principle and grouping principle.

Problem Solving
Map Skills -- I discovered I had the book Map Mysteries by Lisa Trumbauer. It is for grades 2 - 4. We are completing one mystery each week. K. is really enjoying it.

Geometry
We are continuing the book Mirror Magic. This book covers congruence and symmetry.

Subtraction

• K. completed six subtraction problems (to thousands place with borrowing). Then she marked which differences were odd or even, compared the differences using the < or > signs, and rounded to the nearest ten or hundred.
• We played games from the books, Adding and Subtracting Book 1 and Book 2 by Ann Montague-Smith.
• I made up word problems that had to do with comparing. Such as, John had 3 apples. Ken had 7 apples. How many more did Ken have?

Multiplication with Marvelous Multiplication

• We used the squares we made for the four times tables to play a game.
• I put the squares out with the words showing (one, two, three, etc.)
• We took turns tossing tokens.
• We had to give the answer for which ever square it landed on, even if there were already tokens on that square.
• We kept going until we used all the tokens.
• If a wrong answer was given, we took any tokens that were on that square off and put them back in the pot to be thrown again.

• We explored the ten times tables by putting sets of hand prints on a large paper. Each set is a ten, so one set is 1 x 10 = 10; two sets is 2 x 10 = 20; up to 10 sets is 10 x 10 = 100.

• We played the dominos game with a double 6 set.
• Each player has a card with the numbers 1 through 36.
• Players take turns choosing dominos and solving the multiplication equation it represents. That player puts a token on the answer on their card.
• The first person with six in a row wins.
• Dominos with a zero, mean you can put a token anyplace on your card.

Division with Dazzling Division

• We practiced our 3's
• I would give K. a number of colorful game pieces and she would divide them evenly between three circles I drew on a sheet of paper.
• We practiced our 4's
• I printed out pictures of ten animals that have long legs (horse, cow, giraffe, zebra, etc.) then I cut the legs off of them.
• I gave K. four legs. That was enough for one animal. (4 ÷ 4 = 1)
• We continued with 8, 12, 16, . . . 40
• We played computer games to practice our 1's, 2's, 3's, and 4's. K. really liked playing Flurry of Flavors. I liked it because it was not timed, which allowed her to skip count to find the correct answers.
