Math Mammoth Grade 1-B worktext (Light Blue Series) is the student book for the second half of first grade mathematics studies in that Math Mammoth curriculum.

In this part B, the main areas of study are:

* addition and subtraction facts within 10;
* clock to the half hour;
* geometric shapes and measuring length;
* adding and subtracting within 100; and
* counting coins.

Features of the curriculum:

* Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the math, not just learn "HOW" to do it.
* Concepts are often explained with visual models, followed by exercises using those models. These visual models can take the place of manipulatives for many children; however, it is very easy to add corresponding manipulatives to the lessons if so desired.
* The curriculum is mastery-oriented. This means it concentrates fairly long on a topic, delving into its various aspects. This promotes conceptual understanding, as opposed to spiral curricula that often tend to jump from topic to topic too much.
* There is a strong emphasis on mental math and number sense.
* Requires very little teacher preparation, which is a big benefit to most teachers/parents. :)
* The curriculum has no separate teacher's manual nor is it scripted. The introduction to each chapter has some notes for the teacher concerning the material in the chapter. All the instruction is written directly to the student in the worktext, and there also exist accompanying videos where you can see Maria herself teach the material.
* After each chapter introduction, you will find a list of Internet links and resources (games, quizzes, animations, etc.) that can be used for fun, illustrations, and further practice.
* For addition and subtraction facts, you can use our online practice program (free).

A companion to this book, Math Mammoth Grade 1-A worktext covers the first half of 1st grade math (available separately at Lulu). Also available are the answer keys and a book containing cumulative reviews and chapter tests.

Perfect red dress pants
Color: Red, Size: 32
These pants are legit! I got them as a backup to an American flag suit but they are my go-to red pants now. Very vibrant red, well made and good price. The length is purfecttt. I was worried they would be tight but the waist stretches and they look snd feel great on me.

Perfect fit and great quality for a costume
Color: Purple, Size: 34, Color: Purple, Size: 34
These worked perfectly for my husband’s Mayor Humdinger costume. The fit was spot on, the length was just right, and the color matched the picture almost exactly. The fabric doesn’t have any stretch, but it felt nice and well-made, giving the costume a polished look. Overall, a great choice if you need something that fits true to size and looks high quality for a costume.

Great dress/casual pants, but not all colors have the expanding waist.
Color: Green, Size: 31
I ordered the red pair in March for a Lady Gaga concert. I loved the material and they were comfortable and cool in the arena with all the people. In addition, with my 2026 New Year's resolution, I have been running everyday so I have dropped 2 pant sizes and most of my pants now slide off my waist. I really liked these pants because they have an expanding waist (like the newer tuxedo pants style), so even if I fluctuate in size they will still fit well. With summer approaching, I decided that I would replace my old pants that are now too big with these, so I ordered the other 19 colors. Sadly when they arrived, not all the colors come with an expanding waist. The colors that have the expanding waist - Red, Aqua, Light pink, Green, Hot pink, Royal blue, Purple, Navy, and Black. With my waist size still changing, I am hesitant to keep the other colors since they have a very tailored look and if they are slightly too tight or too loose, they will not look as clean. I am returning the other colors since my waist is still changing...I guess 9 out of 20 colors isn't bad.
