The fourth easy worksheet gives first graders another pass at the same key vocabulary with fresh sentence contexts. Part A traces the words share, whole, equal, half, part, and fourth on dotted lines so students keep practicing the spelling that anchors the concept. Part B uses real-life prompts like 'share a pizza equally with one friend, each gets one ___' and 'a rectangle split into 4 equal parts shows ___,' plus the rule that two halves make one whole. Part C tests three statements, including whether four fourths make one whole and whether a rectangle can be partitioned into halves with one line.
