Lessons on telling time

Check out these videos of mine on telling time, meant mostly for grades 2-3, but I will be adding some for 1st grade hopefully soon.

Tell time to the nearest five minutes - grades 2-3

Elapsed time - whole hours - grades 1-3

Tell time using "past" and "till" - grades 2-3

I hope they are of help!

Decimal maze - practice CONCEPTUAL understanding of decimal operations

Here's a decimal MAZE...

Use a calculator, and try to finish with the largest value possible. Looks like FUN!


I feel this would fit best grades 5-7, but even grade 4 students might enjoy it from the perspective of a fun exploration. :)

Math Mammoth International Version


cover for Math Mammoth Grade 1-B Complete Worktext
Currently available for grades 1-4, this version differs from the US version in these aspects:
  • The currency used in the money chapters in grades 1-3 is the Australian dollar. (The download versions for these grades include the chapter on money also for US, British, European, South African, Canadian, and New Zealand currencies.)
  • The curriculum teaches the metric measurement units. Imperial units, such as inches and pounds, are not used.
  • The spelling conforms to British international standards (British English).
  • Page (paper) size is A4.
  • Large numbers are formatted with a space as the thousands separator (such as 12 394). (The decimals are formatted with a decimal point, like in the US version.)

Review lesson for 6th grade: fractions and decimals

In this video lesson of mine, we review how to write decimals as fractions, what to do when an addition or subtraction contains BOTH fractions and decimals, and how to place decimals & fractions on a number line.

The lesson suits best 6th grade math but is of course useful for other students (BIG or SMALL) too.

The 2nd part of this lesson has to do with a word problem concerning unit prices and a "bonus" problem of converting the fraction 1/7 into a decimal.

Hope they are of help! :)

CUTE 1st grade fractions exercise - different colors indeed!

This is what my son did on one of his Math Mammoth pages when studying FRACTIONS in 1st grade math... Look closely at the instruction for question 1d... color both halves, but different colors! It was so cute. :)

This worksheet page is found in my book Introduction to Fractions and also in Math Mammoth Grade 1 Complete Curriculum.

Addition facts within 10 - 1st grade math

Check out my videos on this page at my site! They present an organized and logical method for children to learn their addition facts within 10 using PATTERNS that arise from the number system itself.

Children LOVE patterns, and patterns are the essence of math — mathematics has even been defined as the "science of patterns".

In this method, we study sums with 5, sums with 6, sums with 7, and so on until sums with 10 (also called "number bonds"). These sums or number bonds are not studied in random order, but grouped by the SUM, or the "answer".
