Add three or more numbers up to two digits each<\/strong><\/h2>\n\n\n\n

key points :<\/p>\n\n\n\n

\u2764\ufe0f Add Step by Step<\/strong><\/h2>\n\n\n\n

\ud83d\udc49 Add the first two numbers<\/strong>, then add the next number<\/strong>.
Example:
8 + 5 + 3
\u2192 8 + 5 = 13
\u2192 13 + 3 = 16<\/strong> \ud83c\udf89<\/p>\n\n\n\n

\n\n\n\n

\ud83d\udd22 Add from Left to Right or Right to Left \u2014 Both Work!<\/strong><\/h2>\n\n\n\n

\ud83d\udccc Start anywhere, just add one number at a time<\/strong>.
\u27a1\ufe0f 12 + 7 + 4
\u27a1\ufe0f 12 + 7 = 19
\u27a1\ufe0f 19 + 4 = 23<\/strong><\/p>\n\n\n\n

\n\n\n\n

\ud83c\udfaf Look for Easy Pairs<\/strong><\/h2>\n\n\n\n

\u2728 Find numbers that make 10, 20, or 30<\/strong>.
Example:
6 + 4 + 9
\u2192 6 + 4 = 10<\/strong>
\u2192 10 + 9 = 19<\/strong> \ud83d\ude03<\/p>\n\n\n\n

\n\n\n\n

\ud83c\udf1f Add Tens and Ones Separately<\/strong><\/h2>\n\n\n\n

\ud83d\udca1 Break numbers into tens<\/strong> and ones<\/strong>.
Example:
23 + 15 + 12
\u2192 Tens: 20 + 10 + 10 = 40<\/strong>
\u2192 Ones: 3 + 5 + 2 = 10<\/strong>
\u2192 Total = 40 + 10 = 50<\/strong> \ud83c\udf89<\/p>\n\n\n\n

\n\n\n\n

\ud83e\udde0 Regroup When Needed<\/strong><\/h2>\n\n\n\n

If ones add up to 10 or more<\/strong>, regroup!
Example:
7 + 8 + 6
\u2192 7 + 8 = 15
\u2192 15 + 6 = 21<\/strong>
(15 is already regrouped!) \ud83d\udd04<\/p>\n\n\n\n

\n\n\n\n

\ud83c\udf88 Order Does NOT Change the Answer<\/strong><\/h2>\n\n\n\n

\u2728 You can change the order of numbers.
Example:
4 + 9 + 6 =
9 + 4 + 6 =
6 + 9 + 4 =
All equal 19<\/strong>! \ud83c\udf1f<\/p>\n\n\n\n

\ud83d\udfe9 Use Fingers, Number Line, or Blocks<\/strong><\/h2>\n\n\n\n

\ud83e\uddf1 Tools make adding easier.
\u2714\ufe0f Counting blocks
\u2714\ufe0f Number lines
\u2714\ufe0f Fingers
\u2714\ufe0f Beads
Use whatever helps! \ud83d\ude0a<\/p>\n\n\n\n

\n\n\n\n

\ud83c\udf89 Check Your Work<\/strong><\/h2>\n\n\n\n

\ud83d\udd0d Add the numbers again in a different order<\/strong> to make sure the answer is correct.<\/p>\n\n\n\n

Example:
5 + 7 + 3 = 15
Try:
7 + 3 + 5 = 15 \u2714\ufe0f<\/p>\n\n\n\n
