The Canadian version of grade 5 already is this new edition. The International version is not yet ready; it will be a few months before that becomes available.
By the way... the next grade level I will be revising and revamping is grade 3 — expected to be out in the spring of 2024. It is almost strange (though I realize this is common), when I look at my existing/older work, I immediately start feeling that needs changes. 😄

A recent testimonial... ☺️
"My son is now a sophomore in a brick-and-mortar high school and is taking Pre-Calculus, but I still receive your monthly math news. We read your recommendations about what to use after MM, and he successfully completed Foerster's Algebra supplemented with Math Without Borders, followed by Geometry: A Guided Inquiry supplemented with Math Without Borders. He then took honors Algebra II & Trig through Kolbe Academy using Foerster's Algebra and Trigonometry text. The Pre-Calc class has been mostly review for him and he's looking forward to Calculus.Sales info:
2. Complex fractionscomplex fractions for grades 7 and on up.
Complex fractions are essentially fraction divisions, so all you need to do is divide the two numbers, using the regular rule for fraction division (multiply by the reciprocal of the divisor).
These online exercises give you a special working space for writing out the step where you use fraction multiplication. Your work in this work area will not be checked.
You can choose to include mixed numbers or not. The script will automatically include fractions and whole numbers in the problems.
3. Should your child be allowed to use a calculator for math work?
What do you think?
I feel a calculator is a fantastic tool, but it can also do a lot of harm to children's learning of math — because it can prevent NUMBER SENSE from developing.
And number sense is more important than many people realize! It has been proven to predict a student's success in later years of math, including in algebra.
Developing mental math skills develops number sense. It is the ability to use numbers flexibly — to break them apart and to combine them. For example, if you calculate 4 x 27 by going 4 x 20 and 4 x 7 and adding those, you're using number sense.
Or, if you add 29 + 39 by going 30 + 40 and subtracting 2, you have some number sense.
In Math Mammoth materials, students are introduced to the calculator in 5th grade level, in a chapter dealing with large numbers.
That chapter includes many problems where calculator usage is appropriate. For example, students practice estimating the result with mental math, and then using a calculator to find the exact answer. They also practice choosing whether mental math or a calculator is the best tool for a particular calculation.
These same lessons are also found in the Blue Series book Place Value 5.
From that point onward, Math Mammoth materials show a little calculator symbol next to the exercises where calculator usage is appropriate. That way, the curriculum gently guides them in using a calculator, while not hindering their mental math skills.
What kind of calculator do I need for my child when using Math Mammoth?For Math Mammoth grades 5-6, a very basic calculator will suffice. It needs to have the four basic operations. A phone or a computer calculator will do just fine. In fact, in a few exercises in grade 5, you will need to use a computer calculator that is able to display a large number of digits.
For 7th and 8th grades, the calculator will need to have the square root button.
4. Summer mathIt's that time of year that I want to feature this list of ideas for summer math, again.

At any rate, if you're heading towards a summer break, enjoy it! 😄
