We start with addition, subtraction, and number dictation in kindergarten, and ramp up to 200 daily problems by the end of first grade. If students are able to master their math facts in the primary years, they can devote more time to complex math operations in grammar school and upper school.Memoria Math Challenge: Level B covers addition and subtraction speed drills from 0 to 10 and is organized in an easy-to-use loose leaf format.

Great product!

Would recommend pouring oil into container after pouring in and shaking it up, great additive recommended by some old folks but I would have to say it’s just thick as molasses. Used in 2016 FORD F150 5.0 V8
