Multiplication Shortcuts

-9’s trick using your fingers.
-skip counting.ex.2 4 6 8
-2’s double the number. Ex.2×4=8
-4*15 you do 4×5=20 and then 4×10=40 and 40+20=60.
-find a multiplication fact you know and add from that number.
-anything x11 is same number 2x ex.5×11=55.
-anything x’s 0 equals0.

These are the multiplication equations that I have trouble with:
13×9 and so on…

Multiplication/Division fact families:
10×9=90 9×10=90 90/10=9 90/9=10

Growing Bean Plants

Does the type of liquid put on a bean plant affect the height?
I think changing the liquid will affect the height of the bean plant.
1) Put one cup of soil into a cup.
2) Place one bean seed one cm into the soil,cover seed with soil.
3) Pour 1/4 cup of liquid on to the seed once a day.
*Liquids used are:
Vinegar, milk, miranda, mango juice, water, red bull.
4)record plant height each day.
Observation (day 1):
The soil feels soft and very squishy. Also the soil is white and brown and there are only a few roots. The soil looks like a smashed Oreo and it smells very stinky and it also smells like soil that suffocates people.

Observation (day2):
I observed that the soil feels very rough and squishy.Also it still has only a few roots and it is black and white. The soil smells gassy and it also smells like expired milk.

Observation (day 3):
The soil feels very hard and it is quite rough. It still smells like gas mixed with milk.
