ABC Simplicity

After guided practice with dry erase boards and playing games (repetitive practice with writing numbers in different ways), students will complete this worksheet. *I used this as a formative assessment in order to gauge whether or not to move on or allow students more time to practice this skill.

This vertical number line is used to help students visualize how to "Bridge to 10" or "Make a 10" when subtracting two 1 digit numbers. The focus is finding the "difference" between 2 numbers as opposed to the idea of "taking away". I printed this on colored paper and laminated them for my students to use with dry erase markers. Example: 13 - 8 = ________ *Start at the smaller number (8) on the vertical number line. How many does it take to "Make a 10"? (Answer: 2). Write the number "2".

This activity is beneficial for students as they are able to manipulate objects and visually see how to solve a doubles plus 1 or doubles plus 2 basic addition problem. You will need small manipulatives (I use centimeter cubes) to place in each circle. This is to be used with the Doubles Plus 1-2 Practice Activity Worksheet. Example: 8 + 9 = ____________ *Students will place 8 cubes in the first big circle and the same amount of cubes (because the circles are the same BIG size) in the second

Students will use the RDW strategy to identify how to solve 3 word problems. R: Read the word problem (I prefer 1 sentence at a time). D: Draw a picture of the information provided. W: Write the equation and solve. *Prior Knowledge: Students must be able to add and subtract double digit numbers independently.

We began the lesson by watching a video about place value (each digit has a "home"). We then used our dry erase boards and practiced identifying the value of digits in the ones, tens, hundreds, thousands, and ten thousands. Lastly, students identified the value of each underlined digit up to the Ten Thousands independently using this worksheet.

This activity worksheet is to be used in conjunction with the Doubles Plus 1-2 Circles (on my product list). Students will use manipulatives (and the Circles Activity) to find the "new" math problem to answer each question. Example: 8 + 9 = 8 + 8 + 1 = 17 Prior Knowledge: Students must be able to recall the sums of basic addition "doubles" problems.

Use this BINGO board with the corresponding "Doubles Spinner". Students will practice solving addition problems based on "doubles".

Students will use the "Make a 10" strategy to add two 1 digit numbers. You will need 10 frame boards (magnetic or otherwise) as well as manipulatives to use for the 10 frame board.

Use this spinner with the BINGO-Doubles game. Students will solve basic addition problems using mental math strategies.
