1. From Mathland Daily Tune-Ups Grade 5, second-to-last problem set:

*There are 4 cups in 1 quart. How may cups are there in 6 quarts?

*There are 2 pints in 1 quart. How many pints are there in 4 quarts?

*There are 4 quarts in 1 gallon. How many quarts are there in 4 gallons?

*If there are 4 quarts in a gallon, and you have only 2 quarts, how many gallons is it?

2. From Grade 5 Singapore Math, Primary Mathematics 5B, end of "Measures and Volume" unit:

A rectangular container measuring 12 in. by 10 in. by 11 in. is completely filled with water. After 240 in.^{3} of water are taken out from the tank, what is the height of the water level in the container?

Extra Credit:

1. Estimate the percentage of Singaporean 1st graders who can do the Mathland set.

2. Estimate the percentage of American 5th grade teachers who can do the Singapore problem.

Hi,

I have a fifth grader in California. We had parent teacher conferences yesterday and I have finally come to the conclusion that my husband and I will have to afterschool our daughter in math. She is in a class with only five kids working at or above grade level (she is one of the five) and the teacher is teaching to the average level of the class.

Could you tell me how to get the Singapore math texts?

Thanks

Jane

Hi, Jane,

You can order Singapore Math, cheaply and conveniently, at http://www.singaporemath.com

Sorry about the school woes; hope this helps!

My second grader is using Terc's Investigation in Number Data and Space. It isn't challenging her. Would you recommend Everyday Mathematics or Singapore math or a combination of the two. As a previous responder stated, we'll need to 'afterschool' our daughter in mathematics.

Comment for parent of California 5th grade parent:

Google Math Olympiads and purchase the math olympiads book of problems. Great resource

For 2nd grader parent:

Singapore Primary Math and Miquon were recommended to me back then - use the placement mat'l and scope/sequence charts to determine if it's good for you.

Miquon scope/sequence here:

Worth noting is that this level of manipulation of Imperial measurements is covered midway through Singapore Math 3B. I tell people that Singapore is consistently about half a year ahead of NYC public schools, but this is something else!
