Partial Sums Addition vs Splat

Partial Sums Addition helps students learn and practice the partial sums addition method step by step. The app gives students a visual way to add numbers by working with each place value separately. The partial sums are then combined to find the final answer. Students can solve randomly generated problems or enter their own addition problems. The number of digits can be adjusted for different skill levels. The Partial Sums Method: In the partial sums method, each place value is added separately from left to right. For example, in 764 + 340, the partial sums are 1000, 100, and 4. These are then added together to get the final answer: 1104. Wired.com: “Esa Helttula’s apps are all fantastic for math learning and practice, and aren’t cluttered with mini-games, incentives, or annoying music.” Teacher endorsement: “The math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary. They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice.” — R. Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada Easy to Use: The numbers are aligned automatically so students can focus on solving each column. After the student solves the operation for each column, the correct answer moves into the right place. If the student presses the wrong button, the answer appears above the keyboard but does not move.

Splat-O-Nym is an engaging, independent vocabulary game that helps students learn synonyms and antonyms through four fun activities: Synonym Splat, Antonym Attack, Context Contest, and Lightning Round. Students enter the game in level one of the Synonym Splat activity and move up and down through the 24 levels and between the four game activities based on their performance. The game keeps track of total points, saves the level and points for up to six students between sessions, and generates a Results report that provides a snapshot of a student's performance in the game after each Lightning Round. In all activities but the Lightning Round, students can switch to listening mode and tap on words they would like to hear read for them. Synonym Splat The student splats (taps on) the synonym for each target word presented earning points for correct answers and losing points for incorrect ones. Splatting the correct synonym for four target words in a level (levels 1-12) or five target words in a level (levels 13-24) before tapping two wrong answers moves the student to the next level. Tapping a word that is not a synonym for two target words in a level (before splatting correct synonyms for four target words) moves the student down a level. A splatted synonym remains on the screen with its target word for a moment to reinforce the connection between the words. Target words for which the student tapped an incorrect answer come back after a couple of new target words to give the student another chance to splat the synonym. If the student taps an incorrect word again, the synonym remains on the screen for a moment with its target word to help the student learn the correct answer. Context Contest If the student taps a word that is not the correct synonym for two target words in a level, Splat-O-Nym presents the Context Contest. This game gives the student a chance to earn back the points lost on the two wrong answers by popping the bubble of the synonym of a target word as it is used in a sentence. Antonym Attack When the student earns enough points playing Synonym Splat, Splat-O-Nym presents Antonym Attack. In this activity, the student zaps each of three monsters carrying a target word flag by sliding the correct antonym into the horn and tapping it. Tapping on a word that is not the correct antonym for the target word causes the monster to growl and the word to bounce back to the horn. The student slides and taps word options until tapping the correct antonym for the target word. Splat-O-Nym awards points based on the total number of antonyms tapped correctly the first time. Lightning Round Each time the student accumulates 20 splatted target words, Splat-O-Nym presents a Lightning Round with those 20 target words. During the Lightning Round, the student taps as many synonyms as he or she can in 30 seconds. Splat-O-Nym awards points based on the total number of synonyms tapped correctly in 30 seconds.
