6.9 Subtraction: Regroup Hundreds and Tens – We practiced mentally subtracting numbers in the hundreds to solve problems quickly.
Assignment: Complete homework problems.
We learned that the Distributive Property is a fundamental principle in math that allows you to multiply a number by a sum or difference, distributing the multiplication across each term inside the parentheses.
For addition: a×(b+c)=(a×b)+(a×c)
For subtraction: a×(b-c)=(a×b)-(a×c)
Here, a, b, and c can be any real numbers.
6.8 3-Digit Subtraction: Regroup Hundreds – We modeled borrowing from the hundreds decimal place in order to subtract the tens decimal place.
Assignment: Complete homework problems.
We practiced addition and subtraction facts. We practiced 2-digit addition facts to 100. Saskiia took a practice test covering most of the first grade curriculum.
We learned to specify the position of points in two-dimensional space by ordered pairs in the form of (x, y). X is the horizontal distance from the vertical axis (y-axis). Y is the vertical distance from the horizontal axis (x-axis). The x and y axes intersect at the point (0, 0). The axes are divided into four quadrants as follows:
Quadrant I: x > 0, y > 0 (both coordinates are positive)
Quadrant II: x < 0, y > 0 (x is negative, y is positive)
Quadrant III: x < 0, y < 0 (both coordinates are negative)
Quadrant IV: x > 0, y < 0 (x is positive, y is negative)
6.6 3-Digit Subtraction – We practiced regrouping in both the ones and tens decimal places to solve word problems. We used our understanding of place value and properties of operations to subtract. We persevered to solve word problems.
