Computer Science for All Students

A simple worksheet to practice working with binary numbers. Students will decode a message written in binary code into english characters as well as encode a phrase into binary numbers. Appropriate for grade three to eight. Previous knowledge of binary numbers and counting in binary is important. Counting in binary is a wonderful introduction to computer science. This worksheet serves as a review exercise to check for student understanding. See my other binary number resources in my Computer Sc

This resource is a fun review of binary numbers combined with a word search. There are fifteen binary numbers in a one byte (eight bits) format that the students convert to decimal. They then need to find the numbers in the word search. Please let the students know that there are numbers in the word search that do not match one of the binary numbers. That way, students can’t just look for numbers in the word search and skip the binary conversion. Students should have some grasp of counting in b

This resource is a fun extension activity for anyone teaching binary code with their students. Binary clocks have been around for awhile and demonstrate a practical application of binary code for students. I used this worksheet with third graders without an issue. I would recommend 3-8th grade for this resource. Students should have some grasp of counting in binary in order to complete the worksheet. I have been using a wonderful curriculum, CS Unplugged, to teach our third and fourth-grade cl

This resource is a binary number review worksheet. This worksheet was adapted right out of the CS Unplugged curriculum. The original worksheet used christmas trees instead of Menorahs. I work at a Jewish day school and was looking for some binary review worksheets for my third grade class who was studying computer science concepts. The only worksheets I found were Christmas related, so I came up with this one for Chanukah. Instead of 1’s and 0’s the worksheet uses lit and unlit menorahs to re

This resource is a binary number review worksheet that uses the Ascii (American Standard Code for Information Interchange) code. Instead of 1’s and 0’s the worksheet uses coconuts, whole and half to represent the binary numbers. The story for the worksheet is that a man is shipwrecked on a desert island and uses coconuts to write a message for any passing planes. Students need to decode his message. Students should have some grasp of counting in binary in order to complete the worksheet. The

This resource is a binary number review worksheet. The binary numbers are represented by lit and unlit candles on a Chanukiah (often referred to as a menorah for the Jewish holiday of Chanukah). I work at a Jewish day school and was looking for some binary review worksheets for my third grade class who was studying computer science concepts. The only worksheets I found were Christmas related, so I came up with this one for Chanukah. Instead of 1’s and 0’s the worksheet uses lit and unlit candl
