Level 1 Books Information
Please note that, unlike for Levels 2 and above, Level 1 does not have separate Guide and Practice books. There is only one book per unit.
Level 1 has four units: A, B, C and D. Topics build upon each other from unit to unit.
Keeping track, recognizing small amounts (subitizing), grouping, ten frames, hundreds charts.
Symbols (+ and =), writing addition, finding a missing addend, pairs with the same sum (number bonds), adding more than two numbers, making ten, order (commutativity), and counting up.
Strategies review, using the number line, distance on the number line, adding and subtracting tens, adding by place value.
Reading and writing numbers from 100 to 999, counting by tens, block models of place value, regrouping, and expanded form.
Names and properties, rotations and reflections, combinations and dissections, polyominoes.
Taking away, subtracting 10, counting down, the relationship between addition and subtraction, finding a difference, ordering, and strategies.
Ordering numbers using place value, comparing expressions, finding sums and differences that are equal, compensation strategies.
Comparing lengths, using units, using a ruler, units of time, and reading analog and digital clocks.
Equal amounts, matching (correspondence), symbols (=, <, and >), ordering within 100, comparing length and distance.
Properties, finding similarities and differences, which doesn't belong, categories of numbers (odds, evens, squares, and primes), Venn diagrams.
Completing patterns that use shapes and numbers, skip-counting, and special patterns including the Fibonacci sequence, perfect squares, and triangular numbers.
Understanding directions, describing position, rows and columns, and recognizing order.

I'm pretty sure they are the most engaging math books I've ever encountered, and they pull this off without watering down the content at all (quite the contrary, in fact).
