We practiced finding addition facts to 10 and related subtraction facts. We worked on recognizing them automatically. We wrote two subtraction facts that we are still working to remember. Then we worked on fact families for addition and subtraction. Next, we worked on telling time on an analog clock to the half and quarter hour.
5.4 Model and Record 2-Digit Subtraction – We practiced modeling to solve problems accurately and efficiently. We began to borrow from the tens place to subtract the ones to calculate the difference between two numbers.
5.3 Model Regrouping for Subtraction – We used the base 10 blocks to model borrowing from the tens place. Then we practiced this concept on several problems by drawing the ones blocks.
Assignment: Complete homework problems.
Operations and Algebraic Thinking – We practiced subtraction facts by modeling the break-apart method. Then we worked on word problems where we determined whether to find the sum or difference when setting up equations.
Operations and Algebraic Thinking – We learned to relate addition and subtraction. We determined the addition or subtraction fact based on the sum or difference of the problem.

We practiced finding numbers in a hundred chart, on a number line, and in base ten blocks. We wrote numbers in expanded form and standard form. Then we subtracted and added one and ten to the number. We counted up to 100 by adding 10 to the number. Then we worked on adding 4's, 5's, and 6's.
We practiced number sense and place value activities. We used a hundred chart, number line, and base 10 blocks. We wrote a number in expanded form and we determined where the number fits in the natural numbers. Then we moved on to practice subtraction.
We worked on understanding analog time. We practiced drawing the hour and minute hands on clocks. Then we connected puzzle pieces to match times on a clock.
We practiced dividing decimals by whole numbers. We learned to place the decimal point in the answer directly above its position in the dividend, then perform long division as you would with whole numbers. We continued the process by dividing, multiplying, subtracting, and bringing down digits. When there was a remainder at the end, we added a zero to the dividend and would keep dividing in order to get a more precise answer.
