Staying Within a Grocery Budget

15 February 2012

My little Ca had an ear ache last night and so I didn't get much sleep which in turn led to a late morning. After breakfast I had Ra help me put together our grocery list. I told her what we needed and she wrote it down. At the grocery store I had Ra write down the cost of each item we were purchasing.



With the produce I explained to her that the price (on most items) is based on pounds. The tomatoes were $0.99 per pound and when we weighed the two tomatoes in our sack it was 1 1/8 lb. I drew a pie for Ra to show her briefly what 1/8 means. We added the $0.99 to the $0.12 (for the 1/8 lb) and come up with $1.11 for the tomatoes. She repeated this exercise with the bananas.



At the eggs I showed Ra that they sold them in increments of 6. They had a half dozen, a dozen and one and a half dozen. I had her divide 12 and 18 by 6 and we found it to be 2 and 3. We then divided the price of the 12 eggs by 2 and the price of the 18 eggs by 3. We came up with prices of $0.99 for the half dozen, $0.74 for the dozen and $0.73 for the one and a half dozen. This wasn't really an exercise we needed to do because I always buy the one and a half dozen because that is how many eggs we use in a week, but it was instructional for Ra and I think she enjoyed it.

Since we bought two loaves of bread and two gallons of milk and two bags of cereal I had her add the price of two together. At the end of our trip the list looked like this:

eggs...........$2.19
bread.........$1.98
milk............$4.58
bananas......$1.65
tomatoes....$1.11
cereal.........$6.74
tortillas.......$0.99
tea...........+ $2.66
                 $21.88


When settled at home again I had Ra write her spelling words two times each. I used the synonyms for "symmetry" for her spelling words this week. Her words are:

equal
symmetry
balance
proportion
unity
consonance
symphony
coherence


I worked on her printing with her a little bit, asking her to focus on making her writing neat and exact. I also needed to remind her several times that it is okay to erase, that is why we write in pencil, so we may be able to fix our mistakes. I also had El practice writing with "A" and "1". After that we watched a few videos from Have Fun Teaching and then watched Donald in Mathmagic Land. I used to watch it a bunch as a kid though I never realized how full of information it is!



I did research on line trying to find some Homeschool Co-ops in my area and found that there was a group meeting in an hour for a once a month get together. I hurried my kids out to the car and called my dad inquiring if he would look after the kids for me. He agreed and I met with the wonderful ladies. They were informative and friendly. I only wished that they were a little closer. They gave me information on how to go about locating the homeschool co-ops that would be in my area. I plan on doing some of that tomorrow as I am falling asleep while typing at the moment I need to go to sleep. Sweet dreams!

Valentine Mathematical Symmetry

11 February 2012

Today we made our Valentine's card. It was a fun and super messy but easy to clean up. I started out with having Ra help me figure out if we had enough paper doilies for how many cards we wanted to make. We wrote a list of all the cousins and friends and grandparents we would be making cards for. We agreed that each cousin would only get one card from all four of the kids, the friends would get one card as well. The grandparents however would get one card from each of the kids that could make them on their own, (leaving Em out of the count). The initial count left us with 32 cousins, 6 friends, and 8 grandparents. So our equation looks something like this (32 + 6) + (8 x 3) = 62 . SIXTY TWO! Boy I sure am glad we aren't adding another 60 cards to that with school classes for Ra and El!



I showed Ra the packages of doilies. I had one package of red, one of white and one of pink. There were 16 doilies per package. I asked her to figure out how many doilies we had to make cards with. She added 16 + 16 + 16 and I explained that this was the same thing as 16 x 3. I then asked her if we had enough doilies to use one for every card. She said no, that 48 < 62. I then had her figure out how many more doilies we would need to be able to have one for each card. With an answer of 14 I asked her how many more packages we would need. She answered with one package. We went to the store to get the last needed package.



Finally beginning, we used construction paper, scissors, glue and the doilies to make the cards. I showed the kids how to make a heart by folding the paper in half and cutting half a heart shape around the fold. I used this as an opportunity to explain symmetry. We had fun coming up with other shapes and patterns to cut out using symmetry.  We made hearts, diamonds, rectangles, accordion people, and flowers just to name a few.



We continued the observation of symmetrical objects into dinner time and I plan on continuing to point it out whenever we see it throughout the year.    

Tonight we read The Secret Garden by Frances Hodgson Burnett again. And hey, I even got some reading in of Laddie: A True Blue Story by Gene Stratton Porter.
